STABILIZATION OF FINE SOIL WITH LIME - (1) EXPERIMENTAL STUDY OF THE STABILIZATION OF FINE SOIL WITH LIME

LE TRAITEMENT DES SOLS FINS A LA CHAUX - 1) ETUDE EXPERIMENTALE DES PHENOMENES DE STABILISATION DES SOLS FINS PAR LA CHAUX

The experimental study of the stabilization of silt with lime was undertaken with a view to determining the laws governing the stabilization of fine soil. The time-related evolution of the chemical parameters (consumption of lime) and mechanical parameters (simple compressive strength) is examined for the following variables: quantity of lime used, moisture content of the samples, state of compaction of the samples and nature of the soil stabilized. The results obtained showed that the soil characteristics vary in a simple manner as a function of time and that stabilization takes place in several phases. The curing of the samples at several temperatures demonstrates that each stabilization phase corresponds to a chemical process characterized by its formal activation energy. These considerations on heterogeneous kinetics prove that temperature only accelerates chemical phenomena without changing the nature of the latter. These results justify a policy of accelerated testing to investigate the long-term potential of stabilization with lime over a reasonably short period (1 month). (TRRL)
