ABSTRACT

To expand the application scope of slag-based geopolymer, slag was partially used to replace cement, and the durability of slag-based geopolymer repair materials containing Portland cement (AACS) was investigated. The durability of AACS repair materials was comprehensively evaluated by testing compressive strength, frost resistance, and sulfate attack resistance. The results show that within a certain range, compressive strength increases with the increase in cement content and alkali concentration. Compared with ordinary cement mortar and commercial repair materials, AACS exhibits superior sulfate resistance, frost resistance, and overall durability, making it suitable for projects in cold regions and saline-alkali soils.
