Optimization for Strength Characteristics of Self Compacting Concrete by Statistical Analysis by Taguchi Approach

With growing population, industrialization, and urbanization, there is corresponding growth in the demand for infrastructure. Insufficient compaction dramatically lowers ultimate performance of concrete in spite of good mix design. Placing the fresh concrete requires skilled operatives using slow, heavy, noisy, expensive, energy-consuming and often dangerous mechanical vibration to ensure adequate compaction to obtain the full strength of the hardened concrete. Self-compacting concrete (SCC) is an innovative concrete that does not requires vibration for placing and compaction. The performance of concrete depends on method of curing also. In conventional curing spraying of water/ keeping under wet condition is followed. An attempt has been made in optimizing the strength of self-compacting concrete by statistical analysis by Taguchi approach by selecting water to binder ratio, packing factor, fly ash and super-plasticizers as variable parameters for the study.
