EFFECT OF LOADING CONDITION DURING CURING PERIOD ON UNCONFINED COMPRESSIVE STRENGTH OF CEMENT STABILIZED SOIL

Abstract

An in-situ cement stabilized soil is subjected to overburden pressure under the drained condition, and the magnitude of the overburden pressure varies progressively with stage construction. This paper reviews the strength characteristics of cement stabilized soil cured under different loading conditions, based on unconfined compression tests. The main conclusions are as follows. The unconfined compressive strength declines with elapsed time up to the subsequent loading. When the total overburden pressure is constant, the unconfined compressive strength cured under step loading is lower than that under monotonic loading. Also, an increase in overburden pressure scarcely damages a specimen and its existing cementation properties are preserved.
