crushing strength of basalt rock

Brittle strength of basaltic rock masses with applications to Venus .Jun 25, 1993 . At elevated temperature (∼450°C) and zero confining pressure, reference values for the strength of intact basalt are: Young's modulus, 57 GPa; Poisson's ratio, 0.25; unconfined compressive strength, 210 MPa; and fracture toughness, 2–2.8 MPa m½. Corresponding values for a basaltic rock mass that.strength and deformation properties of granite, basalt, line and .tests indicated,that the rock within each rock type was quite uni- form.

crushing strength of basalt rock,Estimating uniaxial compressive strength of rocks using genetic .

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. Values of unit weight, water absorption.

Comparative Rock Mass Strengths of Basalt and Tuff and Some .

Strength parameters for Calico Hills tuff and basalt are very different, both from their intact equivalents and from each other. Fracturing of either rock type is associated with a marked reduction in the properties of the respective rock masses. For example, the bulk tensile and compressive strengths are reduced by one order of.
