The determination of uniaxial compressive …
The uniaxial compressive strength–point load index relation was studied for pyroclastic rocks. • Very strong exponential relations were found uniaxial compressive strength and point load index. • The results were compared to the studies in the literature.
Uniaxial compressive rock strength determination
Uniaxial compressive rock strength determination Rebound hardness is perhaps the most frequently method used in rock testing to determine uniax-ial compressive strength (UCS). Proceqs RockSchmidt provides not only the possibility of obtain-ing the UCS, but also of sending the complete register data and report direct to the computer.

FOR DETERMINATION OF THE UNIAXIAL COMPRESSIVE STRENGTH OF ROCK MATERIALS 1. SCOPE This method of test is intended to measure the uni- axial compressive strength of a rock sample in the form of specimens of regular geometry. The test is mainly intended for strength classification and characterization of intact rock. 2. APPARATUS (a) A suitable machine shall be used …

The uniaxial compressive strength of a rock under static loading often decreases with an increasing temperature at which the rock has been heat-treated before strength testing. This conclusion is drawn from a great number of experiments [1,2,4,8,9,11,17–19].The higher the temperature is, the lower the strength. Some results for uniaxial compressive strength σ c and tensile strength σ t
Estimating uniaxial compressive strength of rocks …
1. Introduction. The determination of basic mechanical properties of rocks is crucial to a specific engineering project. Several mechanical properties, including uniaxial compressive strength (UCS), have become widely accepted parameters for rock design projects (Baskerville, 1987).From past to present, direct and indirect methods have been used to determine UCS of rocks in field and laboratory.
Measurement of uniaxial compressive strength of …
A new method is introduced to estimate the uniaxial compressive strength of rocks from rock cuttings. The method includes reconstruction of artificial cylindrical specimens from rock cuttings with a density approaching about 80% of the density of intact rocks. For this purpose, drill cuttings are compacted in the standard compaction apparatus. The reconstructed cylinders are then subjected to unconfined …

Introduction Uniaxial compressive strength (UCS) is one of the most widely used rock mechanical parameters in rock engineering like design and construction of foundations, tunneling, slope stability investigations, etc. UCS is also the only parameter to assess rock material strength in Rock Mass Rating (RMR) proposed by Bieniawski (1989). However, uniaxial compression test demands …

Unconfined Compressive Strength Test of Rock
This test method specifies the apparatus, instrumentation, and procedures for determining unconfined compressive strength of intact rock core specimens. This procedure is identical to ASTM D 2938 except that the cores are tested after cutting without grinding, and neoprene caps are used on the specimen ends. Unconfined Compressive Strength Test Procedure Check the ability of the spherical …

12.09.2017 · Uniaxial compressive strength and tensile strength considered as important parameters in characterization of rock material in rock engineering. The necessary core samples cannot always be obtained from weak and block-in-matrix conglomeratic rock. For this reason, the predictive models can employed for the indirect estimation of mechanical parameters.
