Abstract:

Since sources of good quality aggregates are fast depleting, the concrete industry in India needs to prepare itself to use lo cally available aggregates. The use of local materials helps to reduce the efforts to transport material from far away places to si te. Thus, from sustainability point of view, the emphasis should be placed on using locally-available aggregates, even if there are small deficiencies in their quality. It has been demonstrated manier times that desired properties of concrete can be obtain ed by intelligent blending of available aggregates with crushed sand, inert fillers, supplementary cementitious materials and chemical admixtures. The concrete in this paper is produced by utilizing alternative and recycled waste materials such as fly ash and recycled concrete aggregates to reduce energy consumption, environmental impact, and usage of natural resources. In the current papper we will discuss two parameters on which the concrete made by the two-stage mixing approach(TSMA) has been tested and those parameters are flexural stremgth and water absorption. These parametric properties are compared with the conventional concrete with the variation of percentage of recycled coarse aggregates(RCA) and fly ash.
