One of the biggest growing environmental issue is concerning change of climate as result of global warming. The global warming is caused by the emission of the greenhouse such as CO2. Among the greenhouse gases, CO2 contributes about 65% of global warming (McCaffrey, 2002), that release to the atmosphere. From the amounts, around half from carbon dioxide gasses emission was combustion from the process of limestone as the main component standard in making cement. <br /> <br /> <br /> Therefore, it is required efforts supporting suistainability concrete as construction material, by searching dan developing environmental friendly concrete material and construction concrete which more efficient. <br /> <br /> <br /> Expected from research about this geopolymer technology can support expansion efforts of the development concrete material which is more friendly. <br /> <br /> <br /> From research result applying two kinds of composition of different mixture, obtained that composition of mixture content more silica sodium will influence performance of mortar geopolymer. Based on research, optimum compressive strength was 39,43 MPa, obtained by using the composition of mix design two. Compressive strength magnitude average of optimum mortar geopolymer obtained from result of examination by doing treatment method of dry surface, that is 33,12 MPa for mix design 1 and 39,43 MPa at mix design 2. Result of the examination of porosity also shows lower value compared to normal concrete, that is 9,39% for mix design 1 and 7,67% for mix design 2. Dry density of mix design 1 is lower than mix design 2, that is 1467,86 kg/m3 for mix design 1 and 1687,14 kg/m3 for mix design 2.
