An Experimental Study on Self Compacting Concrete

Self-compacting concrete is a fluid mixture suitable for placing in structures with congested reinforcement without vibration. Self-compacting concrete development must ensure a good balance between deformability and stability. Also, compactibility is affected by the characteristics of materials and the mix proportions; it becomes necessary to evolve a procedure for mix design of SCC. The paper presents an experimental procedure for the design of self-compacting concrete mixes. Locally available coarse aggregate of size 20 mm and 12.5 mm, M sand as fine aggregate used in this experimental work. Water binder ratio was fixed as 0.31. Alccofine used as cementitious material in addition of cement. Different trail mixes were prepared with different C. A: F. A and addition of increasing percentage of super plasticizer for obtaining better SSC mix. The test results for acceptance characteristics of self-compacting concrete such as slump flow, V-funnel and L-Box are presented. The cube specimens of size 150mmX150mmX150mm are prepared for compressive strength concrete mixes. The strengths were determined at the age of 7 and 28 days of curing period.
