OPTIMIZING PROPERTIES OF CONCRETE BY SWAPPING M30 SOLID CEMENT WITH ONION PEEL ASH (OPA) AND GROUND GRANULATED BLAST FURNACE SLAG (GGBS) (KEY IJP************110)

Abstract

The suggestion for the use of Agricultural by-products supplies an environmentally friendly strategy for lowering waste and boosting concrete performance. The concrete industry might reduce its adverse environmental effects, facilitate recycling, and use locally sourced, renewable materials. This change minimizes landfill pull and promotes a circular economy in building materials.The focus of the project includes both Ground Granulated Blast Furnace Slag (GGBS) and onion peel ashes (OPA) have been investigated as partial substitutes for cement in concrete. The objective is to reduce decrease dependence on Portland cement, and improve the sustainability of concrete. When onion peels are burned, a byproduct known as onion peel ash is produced. The pozzolanic capabilities are attributed to the high silica content in the ash. GGBS is a byproduct from the steel sector, particularly from the blast furnace method of rapidly cooling (granulation) liquid iron slag. Combining OPA with GGBS: A mixture consisting OPA and GGBS is typically applied; however, this must be changed according to the necessary performance and regional conditions. The GGBS & OPA both are replaced in place of cement by maintaining GGBS as constant with 15% and OPA with ascending follows from 0%, 4%, 8%, 12%, 15% & 20% in M30 Solid. Furthermore, the comparison is made between the regular Solid and Solid mixed with proxies such as 0%OPA+0%GGBS, 4%OPA+15%GGBS, 8%OPA+15%GGBS, 12%OPA+15%GGBS, 15%OPA+15%GGBS, and 20%OPA+15%GGBS.Keywords: Portland cement, Onion Peel Ash (OPA), Ground Granulated Blast Furnace Slag (GGBS), & M30 Solid.
