Elastic Modulus Of Basalt Stone

The uni... queness of the material is that the basalts rockfiber created from natural stone has very good chemical resistance. Fibers with a diameter of 40 microns have 100 resistance to water, very high resistance to alkali and acid. The elastic modulus of the fiber is in the range from 7 to 60 GPa, the tensile ...

Elasticlaboratory measurements andmodeling

moduli of basalts saturated with liquid CO 2are not frequency dependent, suggesting that fluid pore pressures are in equilibrium between 2 Hz and 0.8 MHz. However, when samples are water saturated, the bulk modulus of the rock is frequency dependent. Modeling with Gassmann’s equations predicts the measured saturated rock bulk modulus

Jun 25, 1993  Values of tensile and cohesive strength for the basaltic rock mass are approximately one to two orders of magnitude lower than corresponding values for intact basalt. Temperatures comparable to those at the Venus surface may slightly increase the deformation modulus but decrease the compressive strength of the rock mass.
