Abstract

To reduce the effect of carbon dioxide, geopolymer concrete was extensively developed. The development of geopolymer concrete, generally used material synthesized from the materials of geological origin or by product material such as fly ash which rich of silicon and aluminium. Baggase ash is one of the waste of sugar mill now has been developed to be a potentially material and used as pozzolan for concrete. The baggase ash contains high silicon and aluminium after burning in a certain temperature. This paper present results of experimental program on the density and compressive strength of baggase ash-based geopolymer concrete. The specimens in this research using cylinder with the size of (70 mm x 140 mm). The curing after casting the cylinder uses room temperature. The results show that the density of baggase ash-based geopolymer concrete is lower than ordinary portland cement concrete, and the compressive strength is very low. Therefore, it needs to be developed for the future research to get higher compressive strength of geopolymer concrete
