Paver blocks are often used in alternative functions, such as those in the street as well as other areas of building. This work is mainly focused on the use of GGBS in Geo-polymer concrete (GPC) and using it as a paver block and compare its performance with conventional concrete of grade M30. In this study, compressive tests were performed on the cube specimens at the ages of 7,14 or 28 days. It was observed that the strength of geopolymer concrete is more than strength of conventional concrete at the age of 7 days because of the very fine pozzolana material present in the GGBS which enhance the binding property of the concrete. But the strength of the geopolymer concrete at the age of 28 days is slightly less than that of conventional concrete as in GPC there is polymerization process in which water comes out or reduces the strength of GPC. In conventional concrete strength gain is much at the age of 28 days because hydration of the concrete is completed significantly, or 99% strength of conventional concrete is achieved. Finally, it is found that Geopolymer concrete is a promising construction material due to its low carbon dioxide emission and higher early strength or fire resistance (due to their low levels of chemically bound water) make in better in usage than conventional concrete. As the density of Geopolymer concrete is less than conventional concrete makes the structural weight lesser because the water absorption capacity or porosity of Geopolymer concrete is lower than conventional concrete.
