The aim of this study is analyzing the self-healing capability of High strength concrete (M70) with Silica fumeand Crystalline admixture in four types of environmental exposures i.e. Water Immersion, Wet/Dry Cycles, Water contactand Air Exposure. The percentage replacement of cement with silica fume were: 5%, 10%, 15% and with the addition of1.1 % crystalline admixture .The specimens were pre-cracked at 28 days, in the range of 0.10-0.40 mm and the time setfor healing was 42 days. The result shows that all the mixes have considerable amount of closing ability and strengthregaining capability for all exposure conditions. The concrete with 10% Silica Fume (SF) and 1.1% CrystallineAdmixture (CA) has complete crack closing ability and 100% strength regained capability for WI and W/D conditions.
