Stone Testing

stone specimens are soaked in water at 22°C ±2°C (72°F ±2°F) for 48 hours, wiped, and immediately tested. For general "catalog type" information, the stone is usually tested in a dry condition. The Specifying Authority may specify additional wet testing for a particular project to ensure that the stone …

Compressive Strength - an overview | ScienceDirect Topics

Compressive strength is the standard strength parameter of concrete that can be evaluated under site conditions as well. The most common method is to use cylinder cores drilled off the structure. Momber (1998b) was probably the first to suggest to use the way how a cylinder fails during the compression test as a criterion of the material behaviour during hydrodemolition.

Compressional wave velocities recorded in the direction of applied stress increased sharply within about one-half of the maximum deviator stress and then generally remained constant to failure. The difference in the unconfined compressive strength between the slow and the rapid rates of factor for the granite was less than l; for the basalt, 1 ...

Basalt - Wikipedia

Basalt (UK: / ˈ b æ s. ɔː l t,-əl t /; US: / b ə ˈ s ɔː l t, ˈ b eɪ ˌ s ɔː l t /) is an aphanitic extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the surface of a rocky planet or moon.More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically ...

8. STRENGTH OF SOILS AND ROCKS

shear stress is the shear strength of the soil for the particular value of the normal force N or normal stress (N/A) applied to the soil, where A is the cross sectional area of the soil sample. Fig. 8.8 shows that a dense sand has a greater shear strength than a loose sand and this strength is reached at a smaller value of the displacement.

Brittle strength of basaltic rock masses with applications ...

Laboratory measurements of rock deformation in the brittle regime provide constraints on the response of rocks to stress. These values are essential parameters in tectonic models of near-surface deformation because they influence both the stress state and the conditions for predicting the types and occurrences of brittle structures such as joints and faults.
