The greatest challenge for construction industry in the present times is realization of projects aimed at infrastructure development in harmony with the sustainable development concept. Sustainable development means, judicious use of natural resources for various construction activities. The construction industry, due to its huge size to meet the growing needs of construction activities, is the largest consumer of natural resources such as aggregates, cement (made from lime available naturally) and water etc. To achieve sustainable development in construction sector, it is necessary to replace some of these materials with the alternative materials, which are basically by-products/or waste materials from industries, such as fly ash, granulated slag, silica fume, and their disposal is an environmental threat. These alternative materials not only benefit the environment but also add value to, in the form of enhancement of performance characteristics by judicious selection and proportioning and use. In this study fly ash (FA) and bagasse ash (BA), obtained from fired at controlled conditions, are admixed with Portland cement at different replacement levels. The properties of concrete investigated include compressive strength, splitting tensile strength, modulus of elasticity, modulus of rupture and resistance to chloride ion penetration. Optimum percentage of FA and BA for strength development along with other results are discussed in detail.

Abstract


The greatest challenge for construction industry in the present times is realization of projects aimed at infrastructure development in harmony with the sustainable development concept. Sustainable development means, judicious use of natural resources for various construction activities. The construction industry, due to its huge size to meet the growing needs of construction activities, is the largest consumer of natural resources such as aggregates, cement (made from lime available naturally) and water etc. To achieve sustainable development in construction sector, it is necessary to replace some of these materials with the alternative materials, which are basically by-products/or waste materials from industries, such as fly ash, granulated slag, silica fume, and their disposal is an environmental threat. These alternative materials not only benefit the environment but also add value to, in the form of enhancement of performance characteristics by judicious selection and proportioning and use. In this study fly ash (FA) and bagasse ash (BA), obtained from fired at controlled conditions, are admixed with Portland cement at different replacement levels. The properties of concrete investigated include compressive strength, splitting tensile strength, modulus of elasticity, modulus of rupture and resistance to chloride ion penetration. Optimum percentage of FA and BA for strength development along with other results are discussed in detail.
