Abstract In order to alleviate the pressure of natural resource exploitation and broaden the utilization of low-grade solid waste such as calcium slag and granite stone powder, carbide slag-granite powder based autoclaved aerated concrete (CGAAC) was prepared with calcium slag and granite stone powder as the main calcareous and silica material. The effects of autoclave temperature and constant temperature time on the physical and mechanical properties of CGAAC were explored, and the relationship between different autoclave curing regimes and the phase composition and microstructure of CGAAC was investigated. The results show that at an autoclaving temperature of 195 ℃ and a constant temperature duration of 8 hours, the prepared CGAAC exhibited a compressive strength of 3.36 MPa and a dry density of 529.5 kg/m³. The main hydration products were tobermorite, C-S-H gel, C-S-H(I), calcite and hydrogrossular. Under these conditions, the X-ray diffraction peak of tobermorite gradually intensified, the infrared spectra indicated an increased degree of polymerization of the silicate tetrahedra. The overlapping crystal shapes of tobermorite transformed from flaky to plate-like, interwoven with C-S-H gel, forming a well-networked framework. Unreacted quartz and microcline in the original solid waste, combined with the hydration products, resulted in a denser microstructure of the solid waste-based aerated concrete.

Key words： carbide slag granite powder autoclaved aerated concrete steam pressure curing tobermorite calcium silicate hydrate
