The Development of Geopolymer Concrete Mix and Portable Steam Curing Technique

Geopolymers concrete is environmental-friendly constructions material utilizing waste as the main ingredient in a concrete binder. Various properties of heat-cured geopolymer concrete have shown its suitability for applications such as precast concrete structure. However, the heat-cured method for geopolymers such as steamer generator and a dry-air oven is limited due to the curing system is not mobilized and it is an industrial form. Thus, these types of curing system is not suitable for cast in situ applications. Based on the study carried out, new finding will be proposed to determine the effectiveness of portable steam curing as the new alternative curing technique for geopolymer concrete. Engineering properties of Class F fly ash based geopolymer concrete after curing with portable steam curing method are study and the corresponding results will be compared with the oven curing method. At the end of the research, the portable steam curing method can offer the effectiveness of geopolymer concrete for cast-in-situ alternatives. Besides, the maximum compressive strength of geopolymer concrete with a portable steam curing can be achieved within 24 hours at 80°C
