• As a team member, I was responsible for the gathering materials, documentation and done different tests like Specific Gravity and Fineness on metakaolin which is suitable for the partial replacement of cement.
• The Test results show that metakaolin has similar properties of cement because of that we can partially replace with cement in 4 stages such as 8%, 12%, 16%, 20%.
• On the other hand, we cast M20 grade concrete as per design in different samples like normal M20 and partial replacement samples for 7days,14 days and 28 days.
• The tests were conducted for all samples compressive strength to find normal M20 grade it attain regular strength and partially replacement of cement with metakaolin it attains higher strength in 16% replacement in all the days.
• Finally, Metakaolin is used in cement to enhance strength, improve stability and reduce permeability by reacting with calcium hydroxide. This pozzolanic reaction refines the concretes making denser, more resistant and reduces the environmental impact like carbon emissions and waste.
