摘要
研究了不同掺量的无水石膏和β-半水石膏在不同胶凝材料用量下,对饰面砂浆力学性能、吸水量和抗泛碱的影响。结果表明:石膏掺量较低时,砂浆的抗折和抗压强度较高、吸水量较低、抗泛碱效果较好,但拉伸强度较低;同等掺量时,掺加无水石膏的砂浆抗折和抗压强度较高。
In the paper, under different binders＂ content, the influence of different dosage of anhydrite and β-hemihydrate on mechanical performance,water adsorption amount and anti-efflorescence are studied. The test results show that,with lower gypsum dosage,the tlexural and compressive strength of mortar was high,water adsorption amount was low,and anti-efflorescence effect was good,while the tensile adhesive strength was lower;on the same dosage,flexural and compressive strength of mortar with anhydrite addition was higher.
