By products and wastes are utilized in geopolymer foam concrete

Furthermore, by-products and wastes are utilized in geopolymer foam concrete. Considering the mentioned properties, foam concrete may create an alternative for the commonly used materials such as extruded polystyrene (XPS) boards, which utilization results in unavoidable degradation due to long-term moisture infiltration. However, applying foam concrete as a thermal insulator requires the determination of the optimum parameters that balance the mechanical strength and insulating effect. Crucial in this case is proper density selection, considering the influence of density on the compressive strength and thermal insulation properties is contradictory: increasing the density of foam concrete causes an increase in the compressive strength with a simultaneous decrease in the insulating effect. Furthermore, it should be mentioned that the production of stable foam concrete is determined by many factors, including the type of the foaming agent, method of foam production and addition, mixture selection and design, method of production of the foam concrete, its performance, etc. The foam stability and the relatively low compressive strength of the foam concrete have been recognized as the main challenges in using this material. The overview of the compressive strength of foam concrete with various mixture compositions and densities showed the exponential decrease in the compressive strength with the reduction in the density of foam concrete. The review of research on the compressive strength reported in the literature also revealed that the density of foam concrete usually varies from 400 kg/m3 to 1600 kg/m3, while the target density of lightweight FC usually equals 600 or 800 kg/m3, and for ultra-lightweight FC 400 kg/m3. Only a few studies are devoted to materials of a density lower than 400 kg/m3.
