Laboratory study on partial replacement of conventional construction materials for the construction industry in India

Abstract

The study focuses on the conservation of natural resources by replacing three vital construction materials: (i) Ordinary Portland Cement (OPC) with Marble Dust (MD) (ii) Fine Aggregate (FA) with tile in powdered form and (iii) aggregate with tile chips (TC) for the building construction works. In this present study, the abovementioned materials were used in 10, 20, and 30% as a replacement. As per the current scenario, only limited research papers are available that show what happens when the components are used as individual substitutions for the materials. Due to the lack of supporting evidence for material substitutions in concrete construction, the philosophy of experimenting with the use of mixtures of substitute materials in concrete has emerged. Experiments were conducted with M25 grade concrete, and the best mixes, M24 and M32, are mixes that replace all three traditional components of concrete, achieving strengths of 31.11, 2.76, and 8.0 N/mm2 in compression, 33.33, and 2.76, and 8.25 N/mm2 in flexure, respectively.
