THE TREND OF SOIL TESTING

THE TESTING OF SOIL SAMPLES UNDER RIGID CONDITIONS EXPLAINS THE PERFORMANCE OF SOIL IN LARGER MASSES. THE SOIL TEST METHODS ARE: (1) DOMINANT COLLOIDAL PHENOMENA INVOLVING THE SIZE, SHAPE, AND CHEMICAL COMPOSITION OF THE RELATIVE VOLUMES OF SOLIDS AND PORE WATER IN SEDIMENTS OF DIFFERENT MATERIALS. (2) APPARENT VOLUME OF SOIL FRACTIONS INVOLVING THE EFFECT OF FILM VOLUME ON INDIVIDUAL PARTICLES OF COMPOSITE SOIL. (3) EFFECT OF FILM MOISTURE ON THE STABILITY OF SOIL CONCERNING DECREASING THE RATIO OF FREE MOISTURE TO FILM MOISTURE CONTENT. (4) EFFECT OF ELECTROLYTES SHOWING THAT COMMON METALLIC IONS CAN BE ARRANGED IN THE ORDER OF THEIR ATTRACTION TO WATER. (5) INTERNAL FORCES RETAIN HIGH DENSITY OF SOIL INVOLVING THE BINDING OF CLAY PARTICLES INTO SOIL MASSES AFTER THE WATER IS EVAPORATED. (6) STABILITY OF SOIL IS BEING DETERMINED BY PHYSICAL TESTS TO SHOW THE EFFECT OF MOISTURE AND AIR CONTENT OF SAMPLES ON THE BEARING VALUE AND STABILITY OF SOIL MASSES. THESE TESTS ARE CONSOLIDATION, SHEAR, COMPACTION, AND INDICATOR.
