The cement industry has achieved the harmless and resourceful disposal of incineration fly ash, but the environmental safety of heavy metals during its service life is still unknown. Therefore, the evolution of heavy metal leaching during the wet-dry cycle of the incineration of fly ash after different solidification treatments has been studied. We provide a theoretical basis for the long-term safe use of incineration fly ash after resource utilization.

Co-sintering technology has the potential to solve the above problems. When Municipal solid waste incineration fly ash and fly ash from coal-fired power plants were co-sintering, the effects on the properties of incineration fly ash and used as an admixture was studied.

Polymers play a crucial role in improving the performance of cement-based materials. At the same time, different polymers are added according to specific special requirements to meet the needs of the industry.

Polymer-modified cement-based materials have been widely used in the construction field. Acrylate lotion significantly improves durability, toughness, and bending resistance, especially durability, because the porosity of cement-based materials is reduced, preventing the entry of harmful ions and water. When acrylate lotion was at 20%, the resistance of cement-based materials to chloride ion penetration increased by 40%.
