Abstract

This study utilized polycarboxylate superplasticizer to optimize the workability of phosphogypsum aerated concrete blocks, addressing both the environmental impact of phosphogypsum stockpiling and the issue of short thickening time in these blocks. Utilized mining tailings, phosphogypsum, quicklime, cement, fly ash, aluminum powder, and other raw materials to study the effects of polycarboxylate superplasticizer with different ratio on phosphogypsum aerated concrete blocks. Experimental results showed that when using 0.3% solid content of 20% polycarboxylate superplasticizer with an optimal ratio of polycarboxylate superplasticizer: comprehensive polycarboxylate superplasticizer: Slump retaining agent = 6:2:2, the fluidity of phosphogypsum aerated concrete slurry increased by 30 mm, the 28-day compressive strength improved by 28.6%, and the thickening time extended by 5 minutes. These findings provide technical support for the on-site production of phosphogypsum aerated concrete blocks.
