Effects of Sea Sand Powder on Viscosity and Compressive Strength of Self-Consolidated Concrete

Considering on capability of replacing natural materials in place of industrial resources is a momentous challenge to have more green, sustainable and eco-friendly construction in the world. Coastal areas are rich in sea sand and this material is widely in use in concrete construction due to many advantages. In this study the effect of sea sand powder (SS) on some fresh and hardened properties of self-consolidated concrete (SCC) is investigated and compared with the outcomes obtained from SCC produced with limestone powder (LS) instead of SS. Results indicate that mixes prepared by SS showed especially higher workability in fresh state and almost the same strength results in long term compared to the reference SCC produced with LS; however segregation and bleeding should be controlled.
