N2 - Portland cement is made of the main ingredients are limestone/lime are included in natural resource that is not renewable. So that needs holding replacement with environmentally friendly materials one of which is of geopolymer concrete. Fly Ash is the waste coal combustion products also include natural resources that can not be refurbished Based on data obtained from PT. Z, carbide waste generated in a year on average around 1978.72 m3, it can be put to good use for waste carbide itself has a high CaO content. The composition of the material used in this study was 100% waste carbide, carbide waste 50%: 50% fly ash, as well as 100% fly ash and the activator used as NaOH and Na2SiO3. This study aims to determine how much influence the utilization of waste carbide and fly ash in geopolymer paste in the testing setting time, compressive strength, porosity, UPV, and permeability. The highest compressive strength besides there on the composition of a 100% fly ash is also present in 50% of waste carbide composition: 50% fly ash with activator ratio of 0.5 at the age of 56 days amounted to 39.59 Mpa. The use of fly ash in geopolymer still can not be eliminated 100%, due to the utilization of waste carbide can only be used as an additive or filler.
