Abstract

Self-compacting concrete (SCC) has become more popular in building industry in recent years, due to its superior performance over conventional concrete mix. The main drawback in adopting self-compacting concrete is that there is no proper design mix standard throughout world. The aim of this study is to find out an optimum mix proportioning of high strength selfcompacted concrete for different grades (30MPa – 80MPa). Numerous trial mixes have to be adopted including mineral admixtures like Fly Ash. The strength can be increased by reducing the water- Cement ration and adding sufficient quantity of mineral admixture. Also chemical admixtures are used to improve the workability and to minimize segregation. Tests such as Slump flow test, L-box test V-funnel test, etc., will be conducted in fresh state to estimate the quality of mix. After casting the specimens are tested for three basic strengths such as Compressive strength, Split tensile strength and Flexural strength at 1, 7, 14, 28, 56 and 90th days respectively. With the assumed mix proportion and the tested results, empirical relationship shall be obtained using SYSTAT. Hence for any assumed mix proportion, it is not necessary to cast an SCC specimen, not necessary to wait until the curing period to determine the strength parameter of the specimen by using the established relationships, the strength parameter can be determined. The accuracy of the relationships may be in the order of about 90% to 95%.
