Materials on the Testing of Building Stones of Western Siberia

(Based on data from the Mechanical Laboratory of the Tomsk Technological Institute.)

Siberia, over its enormous extent, possesses significant reserves of various mineral riches. It is quite understandable that, when investigating natural resources for practical purposes, attention is directed first of all to ore deposits. Among non-ore deposits, seams of coal and, in part, graphite are subjected to especially careful prospecting. Non-ore deposits in the form of various building stones attract the attention of geologists, who do not pursue definite material aims here. It is therefore quite natural that information, for example, on coal reserves is expressed in definite—or, as far as possible, definite—figures; there are detailed descriptions of seams, maps, and other materials that provide a basis for discussing the question from the standpoint of the possibility of exploitation, both technically and economically.

As for deposits of building stone, no such data exist. Life, having put forward requirements for this material, resolves the question by feel. In the construction of artificial routes of communication, where stone building materials are required in especially large quantities, they are sought in the nearest places, and, on the basis of tests of the mechanical properties of stone samples, the stone is then quarried in the deposits found and deemed suitable. The results of tests of building stones are sometimes published, and in this way a certain body of numerical material is compiled which, supplementing the data of geological investigations, will in the future make it possible to proceed to the preparation of a more precise characterization of building stones as a construction material.

As indicated above, the use of stone material may be very diverse in purpose: rubble, facing stone, ballast material, cornice and stair slabs, paving stone, sidewalk stone, road-metal stone, and so forth. As to the quantity and consumption of the material, one may judge at least from the following data: for the ballast of a single-track line, per…

one verst requires about 1,500 cubic meters of stone. For macadamizing a wheeled road 7 meters wide, 1,200 cubic meters of crushed stone are needed. For repairing an existing highway, 60 cubic meters per year are needed per 1 verst of roadway. In Siberia, with the very insignificant length of railway lines, with the almost complete absence of highways, as well as of pavements and sidewalks, great work lies ahead in the future in developing and improving means of communication. Without this work it is, of course, unthinkable to speak of the development of local industry on a proper scale. At the same time, in view of the severity of the climate and, consequently, the impossibility in many places of using asphalt paving of streets, the question of developing stone deposits and investigating them becomes very interesting.

It should also be noted here that, in addition to the use of stones as building material, many varieties of them are of interest in technology, for example, for the manufacture of millstones, grindstones, whetstones, rollers for grinding paint, etc.

It is curious to note here that various stone (building, paving, millstone, etc.) is an item of import from abroad. For example, for the period 1901–1913 we have the following table:¹)

TABLE 1.

Year	Thousand poods	Thousand rubles	Year	Thousand poods	Thousand rubles
1901	11311	2440	1908	12564	2151
1902	11014	2440	1909	13571	2573
1903	12027	2598	1910	14977	3052
1904	11128	2737	1911	16107	3609
1905	11813	2599	1912	21160	3628
1906	11639	2336	1913	30670	4900
1907	11109	2225

From this Table 1 it is evident that the import of stone material, being fairly constant in the period 1901–7, began to grow very rapidly from 1908 and by 1913 had increased by 144%.

What has been set forth above convinces us that interest in stone building material must increase, and that thorough investigations of it are highly desirable.

The Mechanical Laboratory at the Tomsk Technological Institute, over a period of more than 15 years of its activity (1904–1920), carried out a series of tests of stone samples that were supplied by various institutions, principally—

¹) Review of foreign trade.

together with the railways; thus, stones for the Siberian Railway were tested here during the construction of the second track and during the reconstruction of mountain sections; samples of stones from the construction of the Altai, Achinsk–Minusinsk, and Kolchugino railways were also delivered here, as well as from the line of the South Siberian Main Line.

Thanks to this, the Laboratory accumulated a fairly considerable body of material on samples of stones from quarries scattered over the area from Novo-Nikolaevsk to Krasnoyarsk and from Tomsk to Semipalatinsk.

Although, unfortunately, the institutions interested in the testing of stone did not always deliver the number of samples that the Laboratory considered necessary, I nevertheless think it useful to publish the results obtained, in view of what has been said above. This is all the more so because, along with determining the mechanical properties of the stones, a petrographic determination of the rock was almost always carried out¹ in the geological cabinet of the Institute.

As was already indicated above, the material subjected to investigation in the Mechanical Laboratory was delivered by various institutions and persons. In most cases the samples were prepared in the quarries and arrived at the Laboratory already in cubic form. Sometimes, however, the suppliers brought pieces of considerable size with the request that samples be prepared by the Laboratory’s own means. The latter has a stone-cutting saw made by the Amsler works. Here the samples were given an approximate cubic form and were finished by hand on cast-iron plates. Usually the samples delivered ready-made had to be corrected in the Laboratory by straightening the right angles. The work was always carried out without blows or shocks, in order to avoid producing fine cracks. The number of samples in the various deliveries was on average 5–6 pieces; only recently, at the insistence of the Laboratory, have 7 samples begun to be delivered in each lot, of which one serves for the petrographic determination of the rock. Stone material, as is known, has an essential drawback—possible heterogeneity; therefore, in order to derive reliable average figures, it is desirable, during testing, to have at minimum three samples for each type of test. But, unfortunately, it is far from always possible to find sympathy in this respect on the part of the supplier, and it was not infrequently necessary to be limited to a smaller number of figures, which makes it difficult to characterize the given material.

As can be seen from the testing tables, sometimes, among three figures obtained when crushing samples of one and the same rock, one figure differs sharply from the other two. In some cases a careful inspection established the presence of a crack that had existed even before the beginning of the test; but sometimes no suitable explanation for the decrease in resistance could be found, and then one had especially to regret the small number of specimens subjected to testing.

Very often, in the delivered specimens, the direction of the bedding was not at all apparent. If the number of specimens was sufficient and the bedding was apparent, the test was conducted in two directions: parallel to the bedding and perpendicular to it.

For each of the delivered batches there were determined the weight of a cubic unit, the degree of saturation of the rock with water, the temporary resistance to crushing, and the resistance to weathering.

The first two operations—the determination of the weight of a cubic unit of stone and of its degree of saturation with water—were carried out simultaneously on two specimens. The latter were dried in a double-walled cabinet until the loss of weight ceased; then the dry stone was immersed in distilled water at a temperature of 15–20°C, first to a depth of 1 cm, and then, after 24–30 hours, completely. The weighing of the saturated stones was carried out until the increase in weight was no more than 0.5%; at this point it was stopped. If the quantity of water absorbed by the stone was \(a\) grams, and the weight of the dry stone was \(Q\) grams, then the degree of saturation with water, in percent, will obviously be equal to

\[ g=\frac{100a}{Q}\%. \]

These figures are given in column 4 of Table A. Since the porosity \(\eta\) of the stone is proportional to the degree of its saturation, the former quantity can be obtained from the latter. Indeed, the degree of porosity referred to the volume of the stone \(V\) will be equal to \(\eta=100a:V\). But the weight of the stone \(Q=V\Delta\), if \(\Delta\) is the weight of a cubic unit; and consequently we shall have

\[ \eta=g\Delta\%. \]

The value \(\Delta\)—the weight of a cubic unit of stone—is given in column 5 of Table A. These data are expressed in grams per 1 cubic centimeter. The volume of the stone is determined by the weight \(v\) of the water displaced by it, and \(\Delta\) is obtained as the quotient of dividing \(Q\) by \(v\), i.e. (both quantities, of course, being taken in grams).

\[ \Delta = \frac{Q}{v} \]

To obtain the values of \(v\), the Laboratory used Jolly’s apparatus, immersing stones that had previously been saturated with water. In its results this method is not inferior to the more painstaking method of finding the volume of a stone by coating the dried specimen with a layer of paraffin. The possible error in both cases is approximately the same. Determinations of the specific gravity of stone with the aid of material ground into powder were not made, since in practice this datum is of much less importance than the value \(\Delta\). To a certain degree of error, the specific gravity can be computed when the value \(a\) is known.

The crushing test for finding the value \(k_2\)—the temporary resistance—was carried out on one of the Laboratory’s machines, most often on Amsler’s 60-ton press. In rare cases, when this machine proved insufficiently powerful, Olsen’s 100-ton machine was used.

For testing, the specimens were dressed on a cast-iron plate in order to obtain correct dihedral angles. The stone was always clamped between cardboard pads—a precaution that is not superfluous, since obtaining absolutely plane pressure surfaces is a difficult and very costly task. The load was applied sufficiently slowly and at approximately the same rate—about half an hour for each specimen. With the exception of special experiments that were sometimes required, the observer usually recorded the maximum load \(P_2\); if the cross-section was \(F\), then the temporary resistance was obtained as the quotient

\[ k_2 = \frac{P_2}{F}. \]

These data are given in columns 7–11 of the tables. As for the stress at which the first crack appeared in the stone being tested, these figures are not given in the tables: first, because they were not recorded in all tests; and second, because, with rare exceptions, the so-called load of the first crack corresponds to reality. To catch, on the colored and often rather dark surface of the stone, the moment at which this crack appears is extremely difficult; usually it is detected by sound, but this indicator is not exact, since very often the first crack forms without any sound at all. Furthermore, the value of the load of the first crack can be of any value only on the condition of entirely precise deter-

of the given pressure surfaces, which, as was already mentioned above, is by no means easy to achieve.

In all those cases when no separate tests of stones in the saturated state were made, the specimens that had been subjected to the weathering test were usually not dried, but were crushed in the wet state.

The values of temporary resistance are shown in kilograms per square centimeter (columns 7–9) and in poods per square inch (column 10). The latter was done for the convenience of those readers who are less accustomed to the measures of the decimal system. Column 11 gives average figures, representing simply the arithmetical means of the experimental data, separately for dry and saturated stone; in addition, the figures of the arithmetical means for each rock are indicated in italics, jointly for dry and saturated specimens.

The weathering test was carried out by freezing in a refrigerator box with double walls. The temperature was maintained at about \(-15^\circ\mathrm{C}\). Stones saturated with water were placed in the refrigerator, where they remained for four hours, after which they were removed and immersed for two hours in distilled water. After thawing, the stone was carefully examined over its surface and by touch. If no appearance of cracks, delaminations, etc., was observed, the freezing operation was repeated further, up to 25 times. Column 12 of the table indicates the number of freezings to which the stone was subjected, and column 13 the results of this repeated freezing, which, if the stone did not withstand the test, manifested themselves most often in the chipping of the vertices of trihedral angles, then of the ribs of the cube and, finally, of its faces.

This usually concluded the determination of the mechanical qualities of the stone being tested. In separate cases, when special requirements were made, various additional tests and determinations were performed. Thus, for example, there were cases of finding temporary resistances to shearing and to bending; loss by abrasion; impact tests; determination of the solid residue in the water in which the stones had been kept after being taken out of the refrigerator. But all these tests, being comparatively few in number, cannot be of general interest, and therefore are not included in Tables A.

As was indicated above, one of the specimens from each batch served for petrographic determination, for which purpose it was sent to the head of the Geological Cabinet of the Institute.

Tables A—on the crushing resistance of stones—were compiled not according to the time of testing, but according to the following classification.

Nos. 1–32 Even-grained, deep-seated (igneous).
Nos. 33–39 Porphyritic (effusive).
Nos. 40–42 Metamorphic.
Nos. 43— Sedimentary.

As for the numbering, the upper number denotes the serial number; the lower number, the number under which the test is recorded in the Laboratory test book.

On the appended map the locations of the deposits are indicated approximately, since very often no information was given as to on which side of the railway line the quarry was located.

Stone building material, in its natural state, is distinguished by an astonishing diversity of rocks, composition, and structure. At a cursory glance at the tables of results of tests of mechanical properties, what strikes the eye is the complete absence of any dependence between such factors as temporary crushing resistance, specific gravity, degree of porosity, resistance to weathering, etc. The observed circumstance is not confined to the results obtained in the Mechanical Laboratory of the Tomsk Institute, but represents a general phenomenon².

Table B presents a summary of average figures, and the data are arranged in decreasing order of temporary resistance for intrusive, effusive, metamorphic, and sedimentary rocks. Siberian trap gives a resistance of 2116 klg/cm² (No. 21) and 740 klg/cm² (No. 28). Quartz sandstone gives 1360 klg/cm² (No. 111) and 430 klg/cm² (No. 109), etc. Such diversity is always observed and may be explained either by the fact that samples from one and the same quarry were taken from different beds, in which case pieces already subjected to weathering may be encountered, or, when obtained from different quarries, by the influence of composition and structure. The influence of the latter factor is quite obvious, for, all other conditions being equal, a fine-grained structure offers greater resistance. The significance of mineralogical composition is almost not manifested. On the contrary, the influence of the latter factor appears in tests for abrasion. In terms of resistance to weathering, the degree of saturation undoubtedly plays a significant role, corresponding to the degree of porosity; in addition, of course, this includes the influence of chemical composition, the degree of solubility in water.

Studying the presented test tables, one may observe that very often a significant resistance to crushing coincides with a high specific gravity.

Of course, here too it is observed that in individual cases the opposite phenomenon occurs. To verify the circumstance noted, I compiled a summary in Table 2, containing data on temporary resistance and specific gravities, with arithmetic means selected between the limits 2,1—2,2, 2,2—2,3, etc.

TABLE 2.

Specific gravity range	Specific gravity, average	Temporary resistance
2,9—3	2,94	1315 kg/cm²
2,8—2,9	2,83	1043 „
2,7—2,8	2,74	955 „
2,6—2,7	2,65	915 „
2,5—2,6	2,55	960 „
2,4—2,5	2,45	865 „
2,3—2,4	2,37	709 „
2,0—2,3	2,18	496 „

Curve A B in Diagram 1 definitely shows a decline in the average figures of temporary resistance together with curve CD (the line of specific gravities). It is true that a certain deviation corresponds to the specific gravity 2,5—2,6.

In view of this, I made an analogous calculation for several results (test data of the Laboratory of the Central Siberian Railway, tests in the Warsaw District of Lines of Communication, data of the Munich Laboratory¹). The results of the calculation are given in the Table.

Central Siberian Railway (2): specific gravity	Central Siberian Railway (2): temp. resistance	Warsaw District (3): specific gravity	Warsaw District (3): temp. resistance	Munich Laboratory (4): specific gravity	Munich Laboratory (4): temp. resistance
2,97	1704 kg/cm²	3,09	2946 kg/cm²	3,00	2902 kg/cm²
2,73	1683 „	2,64	1935 „	2,73	2309 „
2,68	1650 „	2,50	1783 „	2,65	1976 „
2,57	1245 „	2,19	616 „	2,56	1850 „

2,29	994 „			2,07	318 „
1,96	438 „			1,72	70 „

In Diagrams 2—4 these relationships are graphically represented, fully confirming the idea that specific gravity is a known indicator for the magnitude of temporary—

resistance. If the stones tested in the Mechanical Laboratory are arranged according to the structural criterion, namely:⁵

1. Igneous rocks.
   a) normal granite,
   b) the same, formation under increasing pressure.
   c) cataclastic.
   d) destruction of orthoclase into clay.
   e) porphyritic.
   f) almost all constituent parts are destroyed.

2. Sedimentary rocks,—distinguished by cement content: the smallest quantity is evaluated by grade (5) and the greatest by grade (2), then obtaining average figures for the 1st group (igneous rocks) is difficult, since the number of specimens in the groups is very different. One may perhaps compare groups 1 a and 1 d.

Group	Specific gravity	Temporary resistance
1 a.	2.73	1100 klg/cm²
1 d.	2.71	1025 klg/cm²

For sedimentary rocks we obtain the following figures.

Class	Specific gravity	Temporary resistance
V	2.56	927 klg/cm²
IV	2.39	628 klg/cm²
III	2.44	790 klg/cm²
II	2.63	891 klg/cm²

The assumption that, with increasing cement content, resistance decreases is not borne out. The dependence stated between specific gravity and temporary resistance is also confirmed under this grouping.

Of course, no definite conclusions can be drawn from these data, but there is reason to believe that, in testing building stones, it is highly desirable to carry out a more detailed elucidation and, necessarily, in parallel with the testing of mechanical properties, to make a detailed petrographic determination, and moreover with quantitative data. In all cases when the geologist’s prediction does not coincide with the results of the mechanical analysis, an immediate investigation of the phenomenon and clarification of its causes are necessary.
