FACTORS INFLUENCING THE DRYING SHRINKAGE OF CEMENT STABILISED MIXTURES

Volume reduction in soil-cement occurs: (a) during moist curing, (b) when specimen is exposed to the influence of drying, and (c) due to fall in temperature. A detailed study of the various factors affecting the shrinkage during curing has been made by the author elsewhere (bhandari 1973b). This paper investigates the drying shrinkage of cement treated mixtures which occurs as a result of moisture loss on drying. Earlier investigation by the author indicatded the value of factorial method of design and importance of rigid statistical analysis to evaluate the shrinkage during curing of a cement treated soil. Consequently, in this investigation drying shrinkage is affected by such factors as dry density, cement content, period of curring prior to drying, degree of saturation has been investigated by employing the most efficient form of experimental design, viz. Randomised factorial design. The effect of clay content on drying shrinkage has been studied separately. The interdependence of various factors in their effect on shrinkage and indispensability of appropriate statistical techniques to evaluate the drying shrinkage be haviour of cement stabilised soil has been further confirmed. Included in the paper are also the collateral studies between: (a) drying shrinkage and moist cured shrinkage, (b) drying shrinkage, and (c) drying shrinkage and indirect tensile strength. /Author/TRRL/
