Effect of Metakalion and Fly Ash on Properties of Concrete

Abstract

Concrete is the construction material which is used frequently all over the world. It is widely used in infrastructure projects. It is made by mixing cement, water, inert matrix of sand and gravel undergoes several operations such as transportation, placing, compacting, finishing and curing. The ingredients contains active materials like cement, water and inactive materials comprising of fine and coarse aggregates. Metakaolin is used instead of cement in the year 1960 and working with this material has increased in recent years .It has has various pozzolanic properties which brings positive effects on resulting properties of concrete. These properties cause chemical reaction of active components with calcium hydroxide, which is formed as a product of cement hydration. Fly ash and Metakaolin are used as replacement of OPC
