Abstract

The production of cement as a concrete binder increases with the increase in infrastructure development. In the process of producing cement produces carbon dioxide (CO2) gas into the atmosphere which can cause global warming. To overcome these adverse effects, it is necessary to find a replacement material for cement as a binder in concrete. Geopolymer concrete is an alternative to replace concrete that uses cement that is less environmentally friendly. Geopolymer concrete does not use cement as an adhesive, instead, it uses fly ash containing Silica and Alumina which is reacted with alkaline activators to produce a binding material such as cement. Sukabumi is an area that has a lot of fly ash waste that can be used as pozzolan material, several companies use coal as an energy source such as Pelabuhan Ratu power plant and cement factory. Besides several regions in Sukabumi also have sufficient aggregate material used for geopolymer concrete, one of which is a fine aggregate of quartz sand of Sekarwangi, Cibadak District, Sukabumi, West Java, which can produce 15,000 tons of quartz sand per month. This test uses an experimental method in the laboratory-based on SNI and ASTM, rain includes compressive strength, tensile strength, and flexural strength. The test results showed the optimum compressive strength of 32.88 MPa at 14 molar age 56 days. Split tensile strength and flexural test was carried out at 28 and 56 days, the highest split tensile strength value was 3.53 MPa at 14 M at 56 days old, and the optimum flexural strength value was 6.13 MPa, from the test it was found that the higher molarity used then the higher the mechanical strength of geopolymer concrete.
