Rock mass strength is defined by three parameters including unconfined compressive strength of intact basalt and two others related to the degree of fracturing of the material. Experimental results for elevated temperature extend the applicability of these parameters to the near-surface environment of Venus.

New correlations between uniaxial compressive … New correlations between uniaxial compressive strength and point load strength of basalt M. Endait and A. Juneja* Although the mechanical and physical properties of many rocks have extensively been studied, little
Ignimbrite has been classified as extremely porous, whereas basalt is highly porous. Yellow and brown ignimbrite and basalt have been considered as poor strength, while black and gray ignimbrite as very poor strength. This paper attempts to predict the UCS of different types of rocks.
The aim of this paper is to estimate the uniaxial compressive strength (UCS) of rocks with different characteristics by using genetic expression programming (GEP). For this purpose, five different types of rocks including basalt and ignimbrite (black, yellow, gray, brown) were prepared.

3.3. Compressive Strength Because concrete is an excellent material for resisting compressive loading, it is used in dams, founda-tions, columns, arches and tunnel linings where the principal loading is in compression. Strength is usually determined by means of test cylinders made of fresh concrete on the job and tested in compression at various ages.

directed more towards the measurement and use of the shear strength or shearing resistance than towards any other strength parameter. (Bishop, 1966). In the case of concrete, the compressive strength is the most commonly measured strength parameter and this is also true of rock specimens.

Both, high strength glass and Basalt rock FRP rebar hold tremendous advantage over steel, galvanized steel & epoxy-coated steel rebar in key physical and characteristic properties. KODIAK Basalt Rock Rebar has the advantage of being a little lighter than glass, a little higher tensile strength than common e …
Compressive strength - Wikipedia. Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to tensile strength ...
During their research, they noted a rapid decrease in compressive strength as the porosity of the rock increased to about 20% at which point the drop in strength flattened out. Li and Aubertin (2003) observed similar results with a break at about 20 percent [3].

ABSTRACT: Understanding and predicting the intact strength of rock is very important in design of foundations, tunnels, and in other engineering projects. The presence of vesicles within basalt has a direct impact on the unconfined compressive strength (UCS) of the intact rock.
