An Experimental Study on use of Rock Flour and Insulator Ceramic Scrap in Concrete

摘要

Increased construction activity and continuous dependence on conventional materials of concrete making are leading to scarcity of the construction material and increased construction cost. If some of the waste materials are found suitable in concrete making not only cost of construction can be cut down, but also safe disposal of waste - materials can be achieved In the present paper, an attempt has been made to assess the suitability of rock flour and ceramic scrap in concrete making. In the laboratory investigations rock flour has been tried as fine aggregate in place of sand and ceramic scrap has been used as partial/full substitute to conventional coarse aggregate in concrete making. Cubes cylinders and prisms were cast and tested for compressive strength, split tensile strength and modulus of rupture after a curing period of 28 days. The results indicated effectiveness of rock four as fine aggregate and partial replacement of conventional coarse aggregate by ceramic scrap up to 20%, without affecting the design strength.
