Development of Self Compacting Concrete Using Composite Material

Self-compacting concrete (SCC) is an innovative and versatile material in the field of construction. SCC is a unique kind of concrete that can flow and fill form work or mould under its weight without the aid of vibration or mechanical compaction. SCC is accomplished using a specifically formulated mix that contains high-range water-reducing admixtures super-plasticizers and viscosity-modifying agents. In the environment, wastes such as Fly Ash (FA), limestone (LS) Composite material made of fly ash is used in many ways and is subject to a variety of different loading conditions, and so different types of stress develop. Optimum replacement of cement with a combination of FA (30%) and limestone (10%,15%&20%). The durability properties of the different mixes were also assessed using tests for sulphate resistance, sorptivity, water absorption, water impermeability, and porosity. Based on the results, the optimal mix proportion was identified, filling ability, passing ability. The test results for acceptance characteristics of self-compacting concrete such as slump flow; J-ring, V-funnel and L-Box are presented. Further, compressive strength at the ages of 7, 14, and 28 days was also determined and results are included
