Impact of Used Foundry Sand on Concrete’s Characteristics—An Overview

Abstract

Concrete is the most commonly utilized material all over the globe. Nowaday’s construction sector has faced a problem in procuring economical natural river sand due to an increase in urbanization and industrialization. Despite that, many industries are facing problems in effective disposal of their waste products. To overcome these two problems, many researchers have done investigations on the utilization of various industrial byproducts like waste foundry sand, rice husk ash, etc., in concrete. These studies defend the utilization of different industrial byproducts in the manufacturing process of concrete. So, in this way, cost as well as the environment can be saved. This article attempts to review the present literature on in-depth studies that have been undertaken in an attempt to investigate reasonable applications and capability of used foundry sand (UFS) for building construction materials. In the paper, various properties of concrete in which UFS is used as fine aggregate are presented which are broadly named as fresh, mechanical, and durability properties.
