Estimating uniaxial compressive strength of rocks

2013-8-1  The average dry unit weight of basalt is 23.2 kN/m 3. For the ignimbrite, the lowest average water absorption by weight of 10.37% is observed in the yellow ignimbrite, and the highest value of 20.17% in the black ignimbrite. The average water absorption by weight of basalt is 2.58%.
