DEFORMATION AND DESTRUCTION OF SOME DISPERSE SOILS AND POROUS MATERIALS UNDER UNIFORM HYDROSTATIC PRESSURE

EXPERIMENTS WITH UNIFORM HYDROSTATIC PRESSURE UP TO 283 KG PER SQ. CM WITH BALLS MADE OF FOAMY GLASS, GAS CONCRETE, CLAY AND COHESIONLESS SAND IN HERMETIC RUBBER COVERS ARE DESCRIBED. IT IS SHOWN THAT THE DEFORMATION CURVES OF CLAY AND SAND HAVE MONOTONOUS CHARACTER AND RESEMBLE THE NORMAL SOIL-COMPRESSION CURVES; THE DEFORMATIONS ARE SMALL AND THE STRUCTURE OF THE SAMPLES REMAINS UNDAMAGED. DEFORMATION CURVES OF FOAMY GLASS AND GAS CONCRETE CONSIST OF THREE SEPARATE PORTIONS, ONE OF THEM DEMONSTRATES THE PROCESS OF COMPLETE DESTRUCTION OF THE ORIGINAL POROUS STRUCTURE AND THE CONVERSION OF BRITTLE POROUS MATERIAL INTO MINERAL POWDER. SUCH DESTRUCTION OF THE BALLS UNDER UNIFORM HYDROSTATIC PRESSURE IS ONE OF THE MOST CHARACTERISTIC PROPERTIES OF BRITTLE POROUS MATERIALS AND ROCK MASSES (VOLCANIC SLAG, PUMICE, SHELLSTONE) THAT RADICALLY DISTINGUISHES THEM FROM DENSE AND PLASTIC MATERIALS. THE EXPERIMENTAL DATA ARE PRESENTED IN A TABLE. /AUTHOR/
