Abstract

Utilization of fly ash as cement substitution that serves as the connective material has the potential to be used in the manufacture of concrete material. Engineered fly ash becomes an adhesive by a chemical reaction with an activator contains siliceous produces a new type of material called a geopolymer. Geopolymer concrete production allows the full replacement of the cement in concrete construction applications. The aim of this study is to determine the optimum composition mixture and the behavior of the compressive strength of geopolymer concrete due to the fineness of fly ash. F- type fly ash which comes from the power plant Tanjung Enim is filtered into 4 zones before it used. It produces the level of fineness based on fall zone. NaOH and Na2SiO3 used as the activators. The research activities carried out with the manufacture of the cylinder and use the combined activator solution of NaOH and Na2SiO3. The ratio of the activator to the fly ash is 0.25, 0.35 and 0.45. Compaction method with stabbing and curing for the ambient temperature without any special treatment are used for the producing of geopolymer concrete. Effect of fineness level of fly ash based on zones falls (0, 1, 2 and 3) and the ratio of activator/fly ash to conduct compressive strength of geopolymer concrete contribute in increasing the compressive strength of geopolymer concrete maximum of 191.42%.
