Strength Appraisal of Blended Concrete

Concrete plays significance role in the construction industry. All over the world second largest consuming construction material used as concrete rather than water. In the blooming of construction industry blended cement used with supplementary of material like fly ash , slag, metakaolin, because of considerably cost, effectively and sustainability. Today's industrial environment is competitive, it is well known fact thermal power plant wastes causes so many destruction and produces bad impacts on nations economics. The current challenge of concrete industry is to produce high strength and workability supporting material. The use of fly ash enhances durability of concrete and life at effective cost. Fly ash effectively minimizing the quantity of cement content in concrete mix, as one tone of cement saved will reduce an equal amount of CO2 to be discharged into atmosphere. It was also found since last 2-3 decades that utilization of calcined clay in the form of metakaolin (MK) as a supplimentry for mortar and concrete has acceptable interest along with fly ash. In this study evaluate the feasibility of supplementary material in the form of flyash and metakaolin for M20 grade of concrete.
