An Empirical Approach to Design Optimized Self-Compacting Concrete Mixes

CODEN: ACEMF9

Abstract

Self-compacting concrete (SCC) is being used worldwide in the construction industry for new construction as structural and architectural concrete. The properties of SCC are very sensitive to constituent materials. Thus, proportioning and optimization of constituent materials including admixtures is key issue in the mix design of SCC. This paper focuses mainly on an experimental study to select optimum proportions of indigenously available aggregates for SCC and optimize fly ash content in SCC, keeping in view its sensitiveness to water/powder ratio and superplasticizer dosage. The results show that to develop SCC with indigenous materials, the coarse aggregate content should be in the range of 31.63 %–33.97 % of concrete volume and fine aggregates in the range of 38.76 %–47.09 % of mortar volume depending upon powder content. In addition, SCC with 25 %–30 % of fly ash content with respect to powder content requires the lowest amount of superplasticizer dosage and water/powder ratio.
