Effect of the Partial Replacement of Cement with Microsilica and Coarse Aggregate with Crushed Ceramic Tiles on the Properties of Concrete

Abstract

Re-use of waste, otherwise deemed to be of no use, in concrete will lead to green environment. The concrete made so is called sustainable concrete which can also be called as Green concrete. The main focus of this research is to study the strength of concrete with crushed waste ceramic tile and silica fume as partial replacement of coarse aggregate and cement respectively. Rapid construction and total reliance on conventional materials of making concrete are leading to dearth of the materials and increased construction cost. In this research an attempt is being made to find the sustainability of waste ceramic tile as coarse aggregate and silica fume as a possible replacement for conventional aggregate and cement in concrete. In this study we replace the micro silica for cement partially in the percentage of 5%,10%, 15%, 20%, and 20% of coarse aggregate is replaced with crushed waste ceramic tiles. The replaced concrete is compared with the normal concrete. Tests are done following codes of Bureau of Indian Standards. Mix design of M30 grade of concrete is designed by following the specification given in the IS 10262:2009. For all the materials, physical properties shall be determined and fresh concrete is prepared. Concrete is then tested for determination of physical properties in fresh state. In hardened concrete, mechanical properties such as compressive strength & split tensile strength of concrete and durability properties like resistance against acid and alkaline attack would be examined and compared with conventional concrete.
