- Abstract
The implementation of the acceleration of development is a government program in catching up the backwardness and to improve national competitiveness,but the acceleration of development must still pay attention to environmental aspects that exist. One of the efforts in making environmentally friendly concrete materials is the use of geopolymer concrete to minimize negative impacts on the environment so that the benefits derived from the development can also be felt by future generations. Geopolymer concrete is an environmentally friendly concrete technology where the basic material of the concrete does not use cement, but uses the residual combustion of rice shells that contain a lot of silica and uses fly ash left over from burning coal. The method used in testing this geopolymer concrete uses SNI reference to several test of them aggregate testing, normal concrete compressive strength test and compressive strength of geopolymer concrete with a mixture of alkaline solution in the form of sodium hydroxide (NaOH) and sodium silicate (Na2SiO3) carried out at 28 days old. From the test results it was found that rice husk ash cannot be used as geopolymer concrete while fly ash can be used as geopolymer concrete in the ratio of NaOH to Na2SiO3 at 1: 3 and 1: 5 where at a ratio of 1: 3 it increased 2.18% and at a ratio of 5: 1 increased by 41.20%.
