The Role of Granite Waste Powder on Mechanical and Durability performance of GGBS and Metakaoline based concrete

Abstract

Abstract Industrial wastes such as granite waste powder (GWP), GGBS, and Metakaoline (MK) are widely available in numerous Indian states. Due to their pozzolanic abilities, GGBS and Metakaoline were used as a partial alternative to cement in the manufacture of concrete, with constant levels of 40% GGBS and 10% Metakaoline. In addition, to minimize the use of natural resources, granite waste was used as a fine aggregate substitute in various percentages (0, 10%, 20%, 30%, and 40%) on a weight basis, and a PC-300 Maximo-Plats super plasticizer with a dose of 0.3 percent was used to retain the essential workability. For this project, M45 grade concrete with a w/c ratio of 0.36 was used to assess the mechanical properties of blended concrete at the ages of 7 and 28 days. At 28 days of age, durability studies such as water absorption and RCPT tests were conducted. According to the experimental data, the optimum compressive strength of blended concrete was found to be at a 20% replacement of GWP.
