EXPERIMENTAL STUDY ON HIGH PERFORMANCE OF FRC WITH USE OF METAKAOLIN,GGBS AND FLYASH

Civil Engineering

The production of Ordinary Portland Cement (OPC) is increasing in world over. Further, the production of every tonne of OPC generates one tonne of green house gases, (CO2 ) which results in Global Warming. Usage of OPC is more in construction industry as it is a major ingredient in Concrete. As the usage of Concrete is rising year by year in the OPC production and hence the environment is getting polluted added to this undesirable scenario, the natural resources use to manufacture cement are limited. In order to prevent the usage of large amounts of OPC in Concrete, mineral admixtures like Ground Granulated Blast furnace Slag (GGBS), Fly Ash and Metakaolin which are pozzolanic and cementitious in nature are adopted to replace certain percentages of OPC. Experimental investigation is conducted on fiber reinforced concrete with steel fibers up to 1% of weight of binder by casting requisite number of cubes and cylinders of concrete of grade M25 in these mixes OPC is replaced with GGBS, Fly Ash and Metakaolin up to 50%. Mechanical properties are determined by various test like compressive test, flexural test and split tensile test. Test results are compared between controlled concrete and innovative concrete of present investigation.
