Experimental study on partial replacement of cement with ground nut shell ash and cashew nut shell ash concrete

Abstract

Cement concrete is one of the most important building material adopted throughout the world. Generally cement concrete ingredients are cement, sand, hard granite broken stone and water. As the construction of infra structures in developing countries increases, so the requirement of concrete materials are also increased. The strength and durability properties of the concrete depend upon the characteristics of ingredients. In concrete the cement occupies 15 to 20% of volume in concrete, this helps in making a bond between cement and aggregates of concrete and also useful to reduce the pores and creates an ability to make concrete in different shapes and sizes. The cements are normally classified as Portland and Non-Portland cement. The utilisation of additives and various chemical compositions of cement and use of different raw materials have made it available for various construction industries. We need a huge amount of waste material available from the industry such as waste ash, which is used to be as cementitious materials. newlineIn the present life of people, the origin of waste from different sources is being increasing due to the manufacturing of different kinds and ratio of teds of materials. The material waste are dumped day by day either by directly or indirectly. These waste materials are dumped in to the land fill, which is very harmful to the living and non-living things. The handling and disposal of dumping waste are necessary to conservation of surrounding environment newline
