Abstract
According to the World Health Organization, concrete is the third most consumed material by humans after food and water. Concrete consists of cement, coarse aggregate, fine aggregate, and water. In the production of cement, carbon dioxide is released into the environment, which becomes a big problem for environmental protection. Therefore, there is a need to modify the cement with some natural materials with pozzolanic properties. The aggregates, which are extracted from natural rocks and riverbeds, are used mined, it is important to look at alternatives to aggregates in the future. Compressive strength tests, split tensile strength tests after 3, 7 and 28 days were carried out and the flexural strength of the prism was determined, as well as the optimum content of bentonite, with different proportions of bentonite and 60% iron and steel slag replacing the weight of cement and coarse aggregate for a mix of M30 class concrete. It has the problem of disposal as waste and is of ecological interest. Steel slag is an industrial by-product of the steel industry. It is a non-metallic ceramic material formed by the reaction of fluxes such as calcium oxide with the non-metallic inorganic components present in steel scrap. The use of steel slag reduces the need for natural rock as a building material and thus protects our natural rock resources as much as possible. The recovery and recycling of recovered by-products and waste materials have economic and environmental reasons led to a rapid development of slag recycling. This way of using a waste material can solve problems of aggregate shortage at various construction sites and reduce environmental problems associated with aggregate mining. and steel slag, and it was found that there is more room for future research on bentonite dust and steel slag in the future. For our experiment, we need to study the strength of concrete by partially replacing cement with bentonite powder and C. with steel slag. We will try to substitute 0%, 10%, 20% and 30% bentonite powder and 60% steel slag. Tests such as compressive strength, splitting tensile strength and flexural strength are examined, although these are higher values compared to conventional concrete.
