An Approach for Designing Different Sustainable and Economical Concrete Mixes

Abstract

Abstract The design of sustainable and economic concrete mixes can be considered as a potential challenge for building’s engineers and experts. Thus, this paper presents the possibility of designing such concrete mixes using low to moderate amounts of cement and using waste glass and steel slag powders. The use of three groups from concrete mixes have been prepared by control mix, 20% cement replacement, 25% cement replacement and 30% cement replacement by such powders. The compressive strength, flexural strength, splitting tensile strength and the dry density of concrete have been studied. Besides, the economic efficiency for the different concrete mixes has also been studied. The results show that the use of combination of glass and steel slag powders of 20% replacement of cement (10% each) exhibited a significant balance between strengths values and economical consideration.
