Improvement of Engineering Properties of Fibre Reinforced Self Compacting Concrete with Addition of Granite Waste

Construction industry is causing paramount pollution to the ecosystem, which is unbearable as safe and better environment are important and burning concerns of today. Our environmentalists are stressing on 3R's to save the environment, out of these R's reuse is the best and cheapest option. On the same lines, granite a construction material used in flooring or other purposes, ample of waste discarded during polishing and cutting of granite. This granite waste GW when mixed with water poses threat to the environment. So, in the present work GW is used as a partial substitute to cement used in fibre reinforced Self Compacting Concrete. This in length research was carried out mainly to study the behaviour of FRSCC with varying granite waste content. This effect of modifier is studied by detailed experimental program on concrete mix comprising Bulk Density Test, Compressive Strength Test, Split Tesile strength Test and Abrasion Test. Out of these split tensile and compression test helped in reaching the optimum mix. The trend of density increases with GW content as 1.09, 0.97, 4.17 and 4.37 for 5, 10, 15 and 20 GW content respectively. So, addition of GW causes a significant increase in density. The trend of compressive strength is 1.46, 5.84, 8.15 and 14.84 with addition of 5, 10, 15 and 20 GW content resp, so the trend of strength first increases and then decreases with GW content. The trend of tensile strength decreases by 9.57 with addition of 5, 10, 15 and 20 GW content, so the trend of strength decreases with GW content. Whereas the strength increases with increase in fiber content. Loss of thickness as noted from abrasion test is reduced by addition of both GW and PP fibres, so more resistance is developed by addition of these modifiers against abrasion. It was inferred from above tests that at 10 GW content and 0.1 PP content, mix showed best results in all tests. The present work suggests a solution for the environmental problems related to GW disposal and novel way of cement concrete production.
