Usage of waste aggregate on construction

Abstract

Sand collected from Aeolian deposits is expensive due to the unwanted cost of transportation from natural sources. Large-scale exploitation of natural sand creates an environmental impact on society.  River sand is the most commonly used fine aggregate in concrete but due to acute shortage in many areas, availability, cost & environmental impact are a major concern. To overcome from this crisis, the partial replacement of sand with quarry dust can be an economic alternative. In developing countries like India, quarry dust has been rampantly used for different construction purposes but replacement technology has emerged as an innovative development for civil engineering material.
