Preparation and frothing mechanism of froth concrete based on solid waste: A review

Frothed concrete (FC) could be a resent sort of energy-saving and naturally neighborly building material with light weight, great thermal insulation, great sound insulation, waterproof property, and good environmental protection property. At present, global metal ore chemical industry is the pillar industry of national economic development, with a large scale, and the stock of solid waste is increasing year by year. With the deepening of the concept of national energy conservation and emission reduction and green environmental protection, ordinary Portland cement as the primary raw material of traditional froth concrete has become a key factor limiting the production and application of froth concrete. To realize the productive utilization of solid waste such as slag and tailings and prepare green and environmentally friendly froth concrete materials with excellent function, this manuscript discusses the composition of FC raw materials according to the current research status and development trend based on the introduction of FC and its classification. The frothing mechanism of the FC frothing agent was summarized, and the prospect of using solid waste to prepare FC was prospected.
