Experimental Study on Mechanical Properties of Geopolymer Concrete Using GGBS

The aim of this investigation is to develop an environmental friendly construction material using geopolymer concrete. The geopolymer technology is proposed by Davidovits and gives considerable promise for application in concrete industry as an alternative binder to the Portland cement. In terms of reducing the global warming, the geopolymer technology could reduce the CO2 emission in to the atmosphere, caused by cement industries about 80 %. In this technology, the source material that is rich in silicon (Si) and Aluminum (Al) is reacted with a highly alkaline solution through the process of geo polymerization to produce the binding material. The project aim is to use GGBS (Ground Granulated Blast Furnace Slag) in place of OPC and compare its properties with the normal concrete. In the present investigation, it is proposed to study the mechanical properties viz. Compressive strength, Split tensile strength, Flexural strength test on the concrete specimens. Hopefully one day in the near future geopolymer concrete will replace ordinary Portland cement as the most abundant man-made material on earth.
