摘要：Self-compacting concrete (SCC) is a flowing concrete that spreads through congested reinforcement,fills every corner of the formwork, and is compacted under its self weight.SCC requires excellent filling ability, goodpassing ability, and adequate segregation resistance. It can flow with ease in congested reinforcement at beam-columnjunctions and the use of SCC shortens the construction period since it allows faster placement and less finishing time,simultaneously ensuring proper filling of restricted areas with minimum or no compacting leading to improvedproductivity.The present study focuses on utilization of quarry dust and fly ash in SCC as a partial replacement of fineaggregate and cement respectively. In this project, work done on experimental study on fresh and hardened propertiessuch as flow ability, passing ability, compressive, tensile and flexural strength of M40 grade of SCC. In thisinvestigation SCC was made with partially replacing fine aggregate with quarry dust and cement with fly ash. Sixmixes with different percentages of quarry dust (0%, 10%, 20%, 30%, 40%and 50%) as partial replacement for sand30% of fly ash as partial replacement for cement is considered.For each mix workability and hardened tests are carried out respectively. The test results for hardenedproperties are carried out at 3,7,28 days respectively. The results obtained regards the possibility for obtaining the SCCusing quarry dust and fly ash, and also studied its variation in strength properties for different percentages of quarrydust.
