Abstract

The need for the study arises from the requirement to improve the overall utilization of mineral admixtures (Metakaolin (MK) and Fly Ash (FA)) in correct proportions of concrete. The effect of these two mineral admixtures towards the enhancement of the strength of the concrete needs to be researched. A simple mix design procedure is also to be developed for concrete considering the efficiency of two mineral admixtures. Thus the study evaluates the effect of partial replacement of cement by mineral admixtures (MK by 0%, 5%, 10%, 15%, 20%, 25% and fly ash by 10%) on the flexural behavior of reinforced concrete beams and compares it with the beams made with conventional concrete.


Description

Concrete is one of the most common materials used in the construction industry. The popularity of concrete is due to the abundance of raw material, excellence in strength and durability, low manufacturing and maintenance costs, versatility in forming various shapes and its unlimited structural applications in combination with steel reinforcement. However, the concrete industry faces a big challenge due to its vital component cement. The production of cement is an energy-intensive process, and the emission of carbon dioxide during the cement production raises environmental concerns and there are increasing incidents where cement leads to distress in concrete in hostile environmental conditions. These factors have led to the thought of reduction of cement consumption and to intensification of research in exploring the possibility of enhancing strength and durability through the use of mineral admixtures.
