Abstracts: fine aggregate in concrete but due to acute shortage in many areas, availability, cost & environmental impact are the major concerns. Large scale exploitation of natural sand creates environmental impact on society. To overcome from this crisis, replacement of sand with quarry dust can be an economic alternative. In developing countries like India, quarry dust has been rampantly used in different construction purposes but replacement technology has emerged as an innovative development to civil engineering material. The knowledge of structural characteristics and performance of concrete made with this material is necessary for the accurate design of structural elements in construction units. The focus of a good national development is to look inwards with intent to mobilize all natural resources for economic purposes.
