In the new age ground improvement techniques, pertaining to strengthen the weaker soils and to improve the strength characteristics and stiffness of these types of soils, cement stabilization is proved to be more effective. In the cement stabilization, the “curing time” is the key factor in the context of strength gain of the soilcement mixture. Limited literature shows the importance of the curing conditions, mainly time. Also, it has been found that in nature, where the ground water is deeper, the use of such mixtures, especially during grouting are never considered for curing. Keeping this in view, an attempt is made to study the effect of curing time on the strength characteristics of cement treated soil and also to show the engineering behavior in various properties which includes the compaction, compressibility and the shear strength parameters. To achieve this, laboratory tests have been conducted for various types of soils treated with different types of cements, varying the percentages were performed. The results show that the curing time has a significant effect on the unconfined compressive strength and it is found that on the addition of cement content, the engineering properties are also affected.
