Experimental Study on Strength and Durability of M60 mix with Metakaolin as an Admixture in Brine Solution

Concrete is the most extensively used construction material in the world. The addition of mineral admixture in cement has dramatically increased along with the development of concrete industry, due to the consideration of cost saving, energy saving, environmental protection and conservation of resources. However, environmental concerns both in terms of damage caused by the extraction of raw material and carbon dioxide emission during cement manufacture have brought pressures to reduce cement consumption by the use of supplementary materials. An experimental study on the brine solution (3.5 % Nacl) on the hardness properties of M60 with metakaolin. This study includes fresh and hardened properties such as compressive strength at 3,7,28 days and split tensile strength and flexural strength at 7, 28 days of control mix and optimum percentage. This study helps to find out the optimum percentage of metakaolin in brine solution. This study also includes durability of concrete at 56 days and 90 days.
