摘　　要：分别采用表面涂刷防水剂和掺加水泥、矿粉等无机材料的方法对脱硫建筑石膏进行耐水性研究,结果表明,表面涂刷防水剂对石膏试件长期吸水速率及软化系数没有明显改善,只能提高其短时间的耐水性;掺加水泥、矿渣粉等无机材料能显著改善石膏试件的耐水性。The paper adopts the painting waterproof agent on surface and mixing inorganic materials of cement and mineral powder to research the water resistance of the desulfrization gypsum respectively,and proves by the result that the former has no obvious improvement for the long-term water absorption rate of the trials and the short-time water resistance is promoted,while the latter enhances the water resistance of the trials evi-dently.
