Abstract
Concrete is the blended material that typically constitute of cement as binding material, natural sand as fine aggregate & gravel as coarse aggregate. It may or may not constitutes mineral or chemical admixtures. Aggregates consists of 50 to 80 percentage of a conventional concrete mixture. So, their selection is very important to produce ideal concrete strength, durability and workability. Thus, the stipulation for sand obtained from natural resources has increased over years, which has caused scarcity of natural river sand in several regions. Therefore, the need for an alternative for fine aggregate has been increased. On the other hand, ideal use of wastes and their by-products from industries as building materials brings greater significance in terms of cost effectiveness and also equally implies on the conservation of natural resources. So, in this paper an analysis is performed to explore the prospect of using a combination of marble dust powder and quartz in place of natural sand. The replacement ratios of marble dust and quartz are as 5%, 10%, 15%, 20% and 25% of marble dust and quartz by weight. Compression, tension and flexural strengths of concrete analyzed from waste marble dust and quartz has been analyzed in parallel with normal concrete of M25 grade.
