Abstract
nThe incorporation of waste foundry sand into concrete production represents an environmentally conscious and cost-effective approach. This method involves substituting discarded foundry sand for a portion of traditional fine aggregates in concrete mixtures. The primary objective is to address environmental concerns associated with waste disposal while simultaneously achieving cost efficiency in construction materials. By integrating waste foundry sand into concrete, this practice promotes sustainability by reducing landfill waste and conserving natural resources. Through meticulous engineering and mix design, the resulting cost-effective concrete maintains the requisite structural and durability characteristics, contributing to a more eco-friendly construction sector. In an experimental investigation, concrete mixes were prepared with varying proportions of waste foundry sand, ranging from 0% to 60% by weight, for M-30 grade concrete (Portland Pozzolana Cement). These mixtures were carefully manufactured, subjected to comprehensive testing, and compared to conventional concrete in terms of workability and strength. The standard cube specimens, measuring 150 mm x 150 mm x 150 mm, were utilized for testing, with curing periods of 7 and 28 days to assess the mechanical properties of the concrete. Based on the experimental findings, it was evident that an increase in the partial replacement of waste foundry sand resulted in higher compressive strength, signifying its potential to enhance the durability and strength properties of concrete. On the other hand, there was a decline in the split tensile strength as the percentage of waste foundry sand increased. These results underscore the safe and beneficial utilization of foundry sand in concrete, showcasing its potential to improve concrete’s overall performance and sustainability.
