PREDICTABILITY OF CERTAIN PROPERTIES OF SOIL-WATER MIXTURES

RESULTS OF CONSISTENCY TESTS PERFORMED ON CEMENT PASTES, CEMENT MORTARS, AND CONCRETES SHOW THAT THE RELATIONSHIP BETWEEN THE CHANGE IN CONSISTENCY AND THE CHANGE IN WATER CONTENT CAN BE APPROACHED BY A CERTAIN POWER FUNCTION WITHIN PRACTICAL LIMITS. A SIMILAR APPROACH FOR SOIL-WATER MIXTURES WAS RECOMMENDED EARLIER BY THE WATERWAYS EXPERIMENT STATION AS A RAPID OR ONE-POINT METHOD FOR THE SIMPLIFICATION OF THE LIQUID LIMIT TEST PROCEDURE. IN THIS PAPER A SIMPLE PHYSICAL INTERPRETATION OF THIS APPROACH BY POWER FUNCTION, CALLED ASSUMPTION OF INDEPENDENCE, IS PRESENTED. ALSO, THREE OTHER APPROACHES CONCERNING THE RELATIONSHIP BETWEEN THE CONSISTENCY AND WATER CONTENT OF SOIL-WATER MIXTURES ARE ANALYZED MATHEMATICALLY, AS FOLLOWS' /A/ ASSUMPTION OF A LOGARITHMIC RELATIONSHIP, /B/ ASSUMPTION OF A POINT OF CONVERGENCE, AND /C/ ASSUMPTION OF A HYPERBOLIC RELATIONSHIP THE EQUATIONS EXPRESSING THE ASSUMPTIONS CAN BE DERIVED FROM EACH OTHER, THUS, THE FOUR METHODS ARE ESSENTIALLY FOUR DIFFERENT MATHEMATICAL DESCRIPTIONS OF THE SAME PHENOMENON CONCERNING THE SOIL CONSISTENCY AS A FUNCTION OF WATER CONTENT. DATA ARE PRESENTED FROM THE TECHNICAL LITERATURE WHICH INDICATE THAT THE ASSUMPTION OF INDEPENDENCE MIGHT ALSO BE USED AS A SIMPLE APPROACH TO SOIL PROPERTIES OTHER THAN THE CONSISTENCY. /AUTHOR/
