A Study on Strength of Fibre Reinforced Concrete with Partial Replacement of Cement with Quarry Dust and Metakaolin

Amulya S., S. P. S. Ramya

Abstract: Concrete is the widely used construction material in civil engineering field. The demand and cost of cement is increasing day to day, so experts are looking for supplementary materials with the main objective of reducing solid waste disposal and environmental problems, by using waste as supplementary by maintaining the same properties or by enhancing the properties, by using selected materials. Quarry dust (QD) is a waste product produced during the crushing process. It is used in partial replacement of cement in various proportions. This quarry dust which is released directly into environment can cause environmental pollution. To reduce the impact of the quarry dust on environment and human, this waste can be used to produce new products or can be used as admixture in concrete so that the natural resources are used efficiently and hence environmental waste can be reduced. Different types of fibers used to increase tensile strength and reduce cracks in the concrete. The study has been made to evaluate the effect on mechanical and durability properties of M30 grade concrete made with replacement of cement with Quarry dust, (0 %, 10 %, 15 %, 20 %, 25 % and 30 %) and Metakaolin, (0 %, 2.5 %, 5.0 %, 7.5 %, 10.0 % and 12.5 %) by weight and the addition of Steel fibers and glass fibers in different percentages (0 %, 0.5 %, 1 %, 1.5 % and 2 %). For each set mechanical properties were studied by performing Compression test for Cubes, Flexural test for beams and Split Tensile test for cylinders and durability properties were studied by performing Sulphate attack test for cubes.

Keywords: Quarry dust, solid waste disposal, tensile strength, Metakaolin, Compression test, Flexural test, Sulphate
