Effect of void ratio to the strength parameters of sedimentary rocks

This paper is to study the influence of void ratio on the compressive and shear strength of sedimentary rocks at different degree of weathering. As void ratio is related to porosity therefore the present of void ratio should influence the mechanical properties of the porous sedimentary rocks such as...

As void ratio is related to porosity therefore the present of void ratio should influence the mechanical properties of the porous sedimentary rocks such as sandstone and limestone. In order to determine the microstructures including pores and cracks of the samples, sandstone and limestone from different weathering grades were analyzed using photomicrograph analysis method.

In relation to weathering grades, the void ratio of the sedimentary rocks increases as the degree of weathering increases.

In relation to weathering grades, the void ratio of the sedimentary rocks increases as the degree of weathering increases.
