Investigations have been taken up for performance evaluation and hydration mechanism involved in mortar samples prepared using multi blend cements containing fly ash, GBFS and low grade limestone. The detailed investigations carried out revealed that the multi blend cements containing fly ash, GBFS and low grade limestone have performance particularly strength development characteristics comparable to the of control cement. The papers highlights the performance results of mortar samples prepared using multi blend cements, the reaction mechanism involved vis-a-vis scope for simultaneous use of these materials in cement. The results indicated that in a multi blend of fly ash, GBFS, low grade limestone and clinker, up to 65 % of clinker can be replaced gainfully without affecting the performance in a mortar sample. The investigations further revealed that the quality of limestone particularly its Calcium carbonate content does not affect the performance of multi blend cement. Further, experimentation on concrete and its durability are continuing.
