Abstract:
This paper deals with the experiments conducted to study the effect of copper slag, GGBFS (Ground Granulated Blast Furnace Slag), metakaolin on the properties of concrete. While GGBFS and metakaolin are used as partial substitutes for cement, copper slag is used as a partial substitute for fine aggregate. This study investigates the mechanical strength of the concrete in terms of compressive strength, flexural strength, split tensile strength, bond strength and durability performance such as water absorption, porosity and sorptivity. In addition the effect of cement and fine aggregate substitution on the microstructure of concrete is also discussed. The results indicated improved strength properties with decreased cost consumption leading to greater efficiency and reduced river sand consumption as an additional benefit.

Concrete consists of two phases, a cement paste phase comprised of cement, water, and air, and an aggregate phase comprised of coarse and fine aggregates. There are two key considerations when designing a concrete mix. First, the concrete must be workable and easy to cast in the forms in its fresh condition, even when the forms are packed with steel reinforcement. In this condition, it is...

Concrete and asphalt are by far the most common construction materials used today. Concrete is a composite material consisting of cement, water, air, coarse aggregate, and fine aggregates. Fine aggregates are typically sands and coarse aggregates are natural or crushed rocks. Chemical admixtures to modify certain specific properties are also commonly used (i.e., superplasticizers to make...
