Effect of granite powder and crushed ceramic tiles on properties of concrete

Abstract

The fast and improved infrastructural development in India has demanded for large quantities of fine and coarse aggregates for concrete. Also , the ecological imbalance in the nature due to exploitation of natural fine and the coarse aggregates, there is much need to utilize the industrial and demolished construction waste in concrete as an initiative to replace the natural fine and coarse aggregate and also to maintain and develop a sustainable environment through the construction industry. In this experimental study, the effect of granite powder and crushed ceramic tiles as a partial replacement of fine and coarse aggregates respectively in concrete mixes is presented. The laboratory experiment was carried out on concrete M25 grade. Concrete produced from 10%, 20% and 30% replacement of sand with granite powder along with 10% replacement of coarse aggregate with crushed ceramic tiles and 10%, 20% and 30% replacement of coarse aggregate with crushed ceramic tiles along with 10% replacement of sand with granite powder and it is compared with normal concrete. The laboratory program includes workability, compressive strength, split tensile strength, flexural strength, water absorption, Rapid chloride ion penetration and sorptivity. From the experimental investigation, it was found that with the addition of granite powder and crushed ceramic tiles we could achieve good workability but decline in strength with increase in percentage replacement when compared with normal concrete. The optimum percentage of granite powder and crushed ceramic tiles were found to be 10% of the strength.
