摘　　要：掺加水泥及粉煤灰等矿物掺合料的石膏砌块既存在钙矾石型破坏,也存在碳硫硅钙石型破坏,建议在以石膏为主要基材的水泥-石膏体系中,水泥的掺加量宜控制在10%以内;水泥和粉煤灰等矿物掺合料的总掺加量应控制在30%以内,以保证石膏制品的稳定。Exist Ettringite type damage, it has also exist thaumasite type damage in the gypsum block which has added cement and other mineral admixture. In order to ensure the stability of gypsum products, the results show that the addition of cement should be controlled under 10%. The total content of mineral admixture such as flyash in the cement-gypsum system should be controlled under 30%.
