The main motto of starting up this project is to investigate the potential of using crumb rubber and sea shell crushed SBP (Seashell By Product) also called as the coral organic waste material as a partial substitute for coarse sand in the production of concrete paving block (CPB). Laboratory trials were conducted to investigate the effect of crumb rubber particle size. A comparison was also made between CPB and crumb rubber paver block (CRPB) to determine the strength. Styrene-butadiene rubber (SBR) latex was added to the mixtures of crumb rubber CPB and mechanical properties were evaluated. It gives more strength then compared to the normal paving blocks. The accumulations of discarded tyres provoke fire and health hazards. In order to prevent environmental pollution, the policy is evolving and much effort has been put into solving waste tyres problem on a world-wide basis. This will also acts as an environmental friendly blocks. It was found that the natural aggregate can be substituted by SBP (Seashell By-Product) without affecting the delicate balance of a pervious concrete mix. It is evident that the natural resources consistently deplete while the demand for concrete constituent materials still remains increasingly high. Hence, diverse waste materials have been investigated for reuse and/or recycling in full or partial replacement for both fine and coarse aggregate in concrete production. In this we assure that, this will give great impact and thus we give eco-friendly paver blocks.
