DESIGN OF HIGH PERFORMANCE CONCRETE UPTO 120 MPA

The paper represents the study of design of high performance concrete upto 120 MPa. Now A days, Concrete is widely used for construction work. Due to increasing demand of cement it produces environmental pollution because of emission of CO2gas. To reduce these problems it will be beneficial to use supplementary cementious material with cement. It will reduce cost as well as environmental problem. The research is done on HPC by using two supplementary cementious materials such as metakaolin & alccofine. Metakaolin is the made up by the china clay. Metakaolin is calcined between 600⁰ & 850⁰c. Alccofine is the fine material can be used for replacement of cement. By using these materials, the results showed good compressive strength. Design of grade has used of M60,M80, M100, M120. The replacement of cement viz 10% with metakaolin & 5 % with alccofine has taken for mix design.
