Abstract: Self-Compacting Concrete (SCC) is highly workable concrete with high strength and high performance that can flow under its own weight through restricted sections without segregation and bleeding. SCC is achieved by reducing the volume ratio of aggregate to cementitious materials, increasing the paste volume and using various viscosity enhancing admixtures and superplasticizers. It is observed that the behaviour of the design concrete mix is significantly affected by variation in humidity and temperature both in fresh and hardened state. In this study, effect of 5 water-based curing techniques on compressive strength of M30 grade Self-Compacting Concrete (SCC) is discussed. It is observed that immersion method for curing gives maximum compressive strength while the lowest compressive strength is for ice curing. Hot water and sea water give 2nd highest strength at 28 days. It is concluded that, although pond immersion method is best for curing in extreme weather conditions SCC can prove effective for hot weather and sea water conditions. Wet covering method is quite effective giving about 92% strength than that of strength received from immersion method. In cold weather compressive strength gain is quite less about 82%.
