Abstract

This study demonstrated the effect of using nano silica (NS) on the shrinkage properties of low binder ultra-high performance cementitious composites (UHPCCs). For this, UHPCC mixtures were designed with water/binder ratio of 0.20 and total binder of 800 kg/m3. Commercially available NS was used in partial substitution of cement at 0, 0.5, 1, 2 and 3% by weight. The samples produced were tested for compressive strength, autogenous and drying shrinkage as well as weight loss. The results showed that replacing of NS with cement decreased both dry and autogenous shrinkage of UHPCCs. Furthermore, among different NS contents ranging from 0.5 to 3%, UHPCCs containing 2% NS exhibited better results of compressive strength at 180 days.
