Studies on the effect of bagasse ash and binary blend of fibres in high performance concrete

Abstract

The use of supplementary cementitious materials has become an integral part of high strength high performance concrete mix design and high performance fibre reinforced concrete composites which may be natural by-products or industrial wastes Some of the frequently used supplementary cementitious materials SCMs are fly ash silica fume SF Ground Granulated Blast Furnace Slag GGBS Rice Hush Ash RHA and Bagasse Ash BA Bagasse ash an agricultural waste is classified as a highly active pozzolan because it possesses a very high amount of amorphous SiO2 and a large surface area Studies carried out on the performance of supplementary cementitious products with bagasse ash BA waste product of sugar industries are very important which is intended to provide a possible solution to environmental concern related to waste management The possibility of utilizing bagasse ash as partial replacement of cement with various percentage of bagasse ash on the preliminary characteristics of cement paste and mortar were carried out The various properties include Specific gravity Normal Consistency NC of cement Air content and Workability of mortar with different bagasse ash replacements Setting times Soundness and Shrinkage of cement pastes have been studied to ensure the pozzolanic and chemical reactions of bagasse ash Additionally the strength and durability properties of cement mortar have been studied at various bagasse ash replacements Bagasse ash was varied from 0 to 30 at a constant increment of 5 by weight of cement newline
