Examples
- Paper faced gypsum board is mainly made of construction plaster ( calcined with natural gypsum of chemical by product ) and protective paper , mixing with appropriate fiber , modified starch , coagulant agent , vesicant and water
纸面石膏板是以建筑石膏（利用天然石膏或化学副产品石膏煅烧制得）和护面纸为主要原料，掺加适量纤维、改性淀粉、促凝剂、发泡剂和水，经混合、成型、凝固、切断、烘干、切边等工艺制成的轻质建筑板材。 - Paper faced gypsum board is mainly made of construction plaster calcined with natural gypsum or chemical by - product and protective paper , mixing with fiber , modified starch , coagulant agent , vesicant and water . which are mixed , formed , coagulated , cut , dryed and sliced into light construction material . they have advantages of light weight , fire resistance , soundproof , damp proof , heat insulation , easy to operate sawn , nailed or milled an disassemble . it s widely applied in industrial and civil constructions , especially widely used as interior wall , less loading wall , ceiling etc in high buildings
纸面石膏是以建筑石膏利用天然石膏或化学副产品石膏煅烧制得和护面纸为主要原料，掺加适量纤维改性淀粉促凝剂发泡剂和水，经混合成型凝固切断烘干切边等工序制成的轻质建筑板材。 - As a kind of cement retarder , normal setting time and good effect for mechanical properties and soundness of cement can be got when adding desulfurization gypsum in cement , so it can used instead of natural gypsum to produce cement entirely , coal gangue is activated and coal ash desulfurized have good active , can improve cement output and also can depress consumption when them be used as mixed material , have well economic and environmental effects
脱硫石膏作水泥缓凝剂时，水泥的安定性、凝结时间正常，可改善水泥的力学性能，完全可替代天然石膏；活化后的煤矸石和脱硫煤灰具有较好的活性，用作水泥混合材可增加水泥产量、降低生产成本，具有良好的经济和环境效益。 - The activatory coal gangue powder ( acgp ) , ground cement clinker and natural gypsum are mixed by different ratios to prepare blended cement specimens , and its mortar compressive strength performance , water usage for standard consistency , and flowability of mortar are investigated
摘要将经燃烧等过程进行活化处理的煤矸石细粉与磨至一定比表面积的水泥熟料及天然生石膏混合均匀，制成了活化谋矸石粉掺量比例不同的多组混合水泥，并对其胶砂强度性能、标准稠度用水量、胶砂流动度进行了实验检测。
