- ... Originality. The empirical dependences of mechanical properties from gravimetric moisture capacity of the sandstone sample were determined on the basis of the experiments in the laboratory. The regression power function was obtained for stress limit and modulus of elasticity, and for the coefficient of lateral deformation it was logarithmic. The coefficient of lateral deformation at the time of the destruction of some wet samples exceeded theoretically acceptable value of 0.5. ...
