PREDICTING STRENGTH DEVELOPMENT BY CEMENT ADMIXTURE BASED ON WATER CONTENT

In the present investigation, which is interdisciplinary in nature, an attempt has been made to develop a practical method for strength prediction at different ages of clays with cement admixture at their liquid limit water content. The proposed approach is an extension of the well-known Abrams' law which relates compressive strength developed with age to water-cement ratio. Preliminary experiments have revealed that for a particular rest period, viz 7, 14 and 28-days, unconfined compressive strength is a linear function of inverse of liquid limit water content of clays admixtured with a specified percentage of cement by weight of clay. Since the clays at their liquid limit water content have the same pattern of microstructure not prone to any mechanical disturbance, the strength development of different clays at a particular rest period would serve as a normalizing parameter for generalization and prediction of strength development.
