Partial Replacement of Waste Foundry Sand and Recycled Aggregate in Concrete
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 5
Abstract
Low cost concrete production by replacement of fine sand with Foundry sand is a new trend and makes effectively use of Waste foundry sand as engineering material by reducing disposal and pollution problem. Waste foundry sand are byproducts which appears to possess the potential to partially replace regular sand as a fine aggregate in concretes, providing a recycling opportunity for them. With the rapid development of construction industry leading to excessive natural resource consumption and the deterioration of the environment, the contradiction between the sustainable development of construction industry and the shortage of resources will become more and more severe. At the same time, a large amount of solid waste is produced in the process of construction of new buildings every year. Today, the reuse of construction waste has become a common concern issue and deserves deep researches. It can be foreseen that the recycled aggregate concrete as a method of reuse and recycling of the construction waste will bring considerable economic and environmental benefits. This paper identifies a potential use of wastes from foundry industry and construction industry for utilization in construction industry and represents the experimental investigation on utilization of foundry waste as a partial replacement of natural sand by 0%, 20%, 40%, 60% and recycled aggregate as a partial replacement of natural coarse aggregate by 0%,20%,40% and 60%. Concrete mixtures were produced, tested and compared in terms of strength with the conventional concrete. These tests were carried out to evaluate the strengths for 7 and 28 days.
