Abstract
Self-compacting concrete (SCC) represents one of the most significant advances in concrete technology for decades. Inadequate homogeneity of the cast concrete due to poor compaction or segregation may drastically lower the performance of mature concrete in-situ. SCC has been developed to ensure adequate compaction and facilitate placement of concrete in structures with congested reinforcement and in restricted areas. Self-compacting concrete demands large amount of powder (cementitious and pozzolanic materials) content and fines for its cohesiveness and ability to flow without bleeding and segregation. In the present investigation, part of the cementitious material is replaced with pozzolanic material-Fly Ash, and the properties of selfcompacting concrete (M30) in fresh and Hardened states were studied. Initially material study is carried out for the materials such as Portland Pozzolana Cement, Fly Ash, Fine Aggregate, Coarse Aggregate, Water, and Chemical Admixtures. Based on the material properties, the trial mix proportions are arrived for M30 grade SCC with varying Fly Ash percentages. Portland Pozzolana Cement (PPC) was partially replaced with various percentages of class F Fly Ash (FA), such as 0%, 10%, 20%, 30% and 40%. Properties of fresh concrete are investigated by means of slump flow test, J-ring test, and L-box test. Properties of hardened concrete are investigated by means of compression test on cubes and splitting tensile test on cylinders for 7 , 14 and 28 days curing periods
