摘要: |
利用脱硫石膏开展了地面自流平材料试验研究,结果表明,以α半水石膏为基料,掺加石英砂以及减水剂、缓凝剂、消泡剂等外加剂可制备石膏基自流平砂浆,且该自流平砂浆流动度、抗折强度、抗压强度和拉伸黏结强度等主要技术性能指标均达到JC/T 1023—2007《石膏基自流平砂浆》标准要求. |

Abstract: |
Self leveling floor material with flue gas desulfurization(FGD) gypsum was studied. A new kind of gypsum based self leveling mortar with fine fluidity, high strength, was developed with semi hydrated gypsum by mixing quartz sand, water reducing agent, retarder, water retaining agent, antifoaming agent and ethylene vinyl acetate(EVA) copolyment. The tests show that the main performance of this mortar reaches or exceeds the requirements specified in the standard of JC/T 1023—2007, such as fluidity, compressive strength,flexural strength and tensile strength. |
Key words: desulfurization gypsum self leveling fluidity adhesive strength |
