Analysis of a New Type of Concrete that Partially Replaces Cement with GGBS and Glass Powder

Abstract: With the exponential growth of industrialization, industrial by-products are also increasing day by day. One of the byproducts of the steel industry is ground granulated blast furnace slag (GGBS). In addition, GGBS is a good cement mortar due to its durability and strength, and glass waste is a waste material that can replace cement. After 28 days, the pozzolanic reaction between cement hydration and glass powder showed that cement replacement did not affect the compressive strength of concrete. The use of GGBS and waste glass powder (WGP) is the focus of this article. In this experiment, slag (GGBS) and mineral additive (WGP) were used instead of cement by weight. To examine the differences in concrete properties, the differences between glass powder and GGBS were added to the cement. The results regarding air entrainment were compared with partial replacement of glass powder and GGBS. We examined the strength of concrete with the addition of WGP (5%, 10%, 15%, 20%& 25%) to the M40 mixture. Additional cement can be replaced with additional materials such as 40 with GGBS (5%, 10%, 15%and 20% weight cement) at the desired WGP percentage change. Splitting tensile strength, flexural strength and compressive strength tests were conducted. The tests showed that the combination with one sample had better effect than the combination model.
