Abstract
In today’s developing countries work with concrete is not a big deal but to find various admixtures which will help in improving various properties of concrete is a work to be focused. Mineral and Chemical admixtures are generally used to increase the various properties of concrete. Here various properties of concrete are workability, strength which includes compressive strength, tensile strength and bending strength and durability of concrete. This paper discusses the benefits of using different types of chemical admixtures and their effect on the different properties of concrete. The effect of using chilled water for preparing concrete and the effect of high temperature on the concrete is also discussed in this paper. The admixture is generally added in relatively small quantity ranging from
0.005% to 2% by weight of cement. Over use of admixtures have detrimental effects on the properties of concrete.
