Utilizing Mineral Industrial Waste as Additives for Improving Concrete Characteristics

Abstract

Concrete is the most widely used construction material and, for the most part, is produced using non-renewable natural resources and energy intensive processes which emit greenhouse gasses. There exists an opportunity to improve the sustainability of this industry by further exploring the use of alternative materials on the contrary, the amounts of solid waste, especially industrial byproducts are increasing dreadfully due to population growth and increase of economic activities. There is an increasing need to come up with innovative ideas to recycle the generated waste and to use it developing useful materials such as concrete. This study examines the suitability of industrial wastes as a possible substitute for cement. Experiments were carried out to determine absorption water, slump, density and the compressive strengths of concrete with crushed ceramic waste red bricks, pottery, iron flings and aluminum flings, and to compare them with those of control mix concretes. Using 10% of each waste, Test results indicated that red brick (RB) wastes and Iron filings (IR) pumice concretes had good compressive strengths. Furthermore, it was found that water absorption of aluminum flings(AF) was Higher than that of control mix and Pottery (P) concretes was lower than that of control mix. Test results also showed that higher volume was obtained from aluminum flings(AF) than control mix. And using 5%,10% and15% of chromium waste from tannery industry replacement cement and aggregate in concrete mixes .Altogether, our results are very promising indication that there is a strong potential to recycle some of the industrial waste and to use them in a future industry of environment-friendly concrete
