Concrete will be much sturdy and multipurpose moldable construction material. It is composed of sand, cement,and aggregate mixed with water. The water &cement together create a mixture that covers the aggregate & sand. The cement sector is the3rdbiggest industrial source of pollution emitting over 500,000 tons per annum of CO2, sulphur dioxide, oxide, and carbon monoxide gas. Researchers all over the world have started giving their best effort on the extension of incomplete supplementation of normal Port-land cement with minerals by naturally occurring, manufactured, or manmade waste. Numerouskindsof pozzolanic materials fly ash, metakaolin, silica fume, blast furnace slag, etc. are at hand that have cementitious properties. Mixing these materials with normal“Portland cement” might enhance the mechanical & cement properties of cement. Now a day, metakaolinutilization will be developing high popularity in incompletecementreplacement because of its fineness in enhancing numerous factors &strengths of concrete &mortars. Well in several types of research it has been seen that further addition of fibers (natural or man-made) increases concretes structural integrity. Fibers are small pieces providing reinforcement and certain other properties; they might be flat or circular. The fiber will be frequently defined by a suited factornamed aspect ratio. The fiber aspect ratio will be fiber length ratio to diameter.
