Partial replacement of cement and fine aggregate by recyclable materials in paver blocks

Abstract

Cement concrete paving blocks are precast hard products complete out of cement concrete. The product is made in various sizes and shapes like square, round, Zig Zag and rectangular blocks of different dimensions with designs for interlocking of adjacent tiles blocks. In our project industrial waste materials like quarry dust and foundry sand are used as partial replacement of fine aggregate and Fly ash with using coconut fibre for partial replacement of cement. Industrial waste materials and fly ash with coconut fibre will be replaced in various mix proportions and also asses the compressive strength of paving blocks over different time intervals. Finally we compare the quarry dust, foundry sand and fly ash and coconut fibre with normal mix of our paving blocks and cost analysis also will be done.
