Abstract
Concrete is the most widely used man-made construction material in the world. It is a composite material. The strength, durability, workability and other characteristics of the concrete depending on the properties of its ingredients. The use of admixture has become inevitable in terms of improving the characteristics of concrete in both fresh and hardened states to achieve the desired results. In recent years, the demand for admixture mixes has been frequently experienced in the ready-mix concrete industry owing to longer delivery distances or to delays in placing because of problems at the site. A good number of researches are been carried out to study the effect of different type of admixtures on the properties of concrete. This paper helps to achieve an understanding of how a normal concrete mix may behave under different admixture conditions. It helps to investigate the effects of different admixtures one water reducer and other retarders on fresh and hardened properties of concrete. Journal aims at suggesting methods to improve the quality of concrete and thus reducing the cost of overall construction.
