A Review: GGBS as a Cement Replacement in Concrete

Abstract Numerous infrastructures have been effectual on the list with the demands of Malaysia’s economic growth due to the country’s explosive growth. As a result, demand for cement has increased, prompting one of the country’s largest cement producers to increase production. Cement production necessitates a significant quantity of finite supplies, such as stock and hydrocarbon deposit which is expected to produce 5-6 percent of all carbon dioxide greenhouse emissions. This paper emphasizes the viability of GGBS for certain value in cement, as implied by earlier studies. GGBS is a waste product deduced from the iron and steel industries. The use of GGBS as a cement replacement in concrete is desirable since it has equivalent cement fineness and cementitious properties. The specific gravity, specific surface, GGBS’s chemical composition and impact of GGBS on water absorption were discussed in this study. Replacing GGBS in concrete production reduced the highest point heat of hydration rate and time. The use of GGBS as a partial cement substitute in the range of 30% to 60% developed strength at longer hardening periods.
