Application of Seawater and Sea Sand to Develop Geopolymer Composites

Abstract

Worldwide, concrete is predominantly used as a versatile building material with its highest consumption on the earth. Nevertheless, its exigency accelerates day by day exhausting restricted natural resources in its manufacturing. Consequently, in order to prevent the degradation of these natural confined aggregates resources, it’s highly essential to employ other alternative profuse materials in their place. On the one hand, the sea Sand is existing in huge quantity below seas and oceans while on the other hand, restricted river Sand resources are being quarried haphazardly and hence reaching to their end. What’s more, to flashlights on, the production of every ton of cement contributes to the emission of an almost equal quantity of CO2 with high energy consumption. Also, it is worth mentioning that freshwater resources are in the limited quantity and, therefore, mankind is not getting sufficient fresh water even to drink in some corners of the world. In present experimental investigations, all the above burning dilemmas are kept in mind and hence, the sea Sand is used as an alternative to river Sand whereas sea water is used instead of distilled water for laboratory investigations on the properties of Geopolymer concrete and mortar in the total absence of Ordinary Portland Cement. The results demonstrated that the sea sand and seawater have no doubt affected the strength of Geopolymer concrete and mortar but just insignificantly.
