Abstract:
PROPERTIES OF A SOLIDIFIED SOIL ARE DEPENDENT UPON THE REACTION OF THE SOLIDIFIED MATRIX TO THE FORCES THAT OPERATE UPON IT. THE QUALITATIVE CHARACTERISTICS OF THE RESPONSE DEPEND ESSENTIALLY UPON THE CHEMICAL STRUCTURE OF THIS MATRIX WHEREAS THE ACTUAL VALUES DEPEND NOT ONLY ON THE CHEMICAL STRUCTURE BUT ALSO ON ITS GEOMETRICAL STRUCTURE (I.E., ITS DISTRIBUTION THRU THE SOIL MASS). ALTERATION OF THIS GEOMETRIC STRUCTURE CAN OCCUR ONLY WHEN VISCOUS FLOW WITHIN THE MATRIX IS POSSIBLE. THUS, MATERIAL IN WHICH VISCOUS FLOW DOES NOT OCCUR (E.G., CEMENT) SHOULD BE PLACED IN AS DENSE A STATE AS POSSIBLE SINCE LITTLE SELF DENSIFICATION IS POSSIBLE. MATERIALS WHICH DO POSSESS VISCOUS FLOW (E.G., CALCIUM ACRYLATE) CAN BE PLACED AT LESS THAN MAXIMUM DENSITY SINCE THE CONTRACTILE FORCES OF DRYING CAN CAUSE SELF-DENSIFICATION. FOR THIS TYPE OF MATERIAL TO BE SUITABLE AS A STABILIZING AGENT, THIS PROPERTY OF VISCOUS FLOW MUST EVENTUALLY BE REMOVED EITHER BY CHEMICAL REACTION OR A PHASE CHANGE. EXPERIMENTAL DATA ARE PRESENTED TO DEMONSTRATE HOW THE STRUCTURE OF VARIOUS STABILIZING AGENTS AFFECT THE PROPERTIES OF SOLIDIFIED SOIL THROUGH THE ABOVE MECHANISMS. IT IS SHOWN THAT STABILIZERS CAN BE CLASSIFIED INTO ONLY A FEW GROUPS EACH OF WHICH WILL POSSESS TYPE CHARACTERISTICS. THE IMPLICATIONS OF THESE FACTORS ON THE FUTURE OF SOIL STABILIZATION IS DISCUSSED. /AUTHOR/
