低温(10℃)-干湿循环下水泥砂浆抗硫酸盐侵蚀试验研究
Experimental Study on Sulfate Attack of Cement Mortar under Low Temperature(10 ℃)and Dry-Wet Cycle
摘要
Abstract
At low temperature(10 ℃)and dry wet cycles under the dual environment, experimental study on sulfate resistance of cement mortar specimens than different cementitious materials for different water cement, the water cement ratio by 0.5 and 0.36 respectively, the cementitious materials of ordinary portland cement,anti sulfur acid and Portland cement in ordinary portland cement was added to 15% +1%and 15% +3%powder of wollastonite powder and silica fume.The results show that at low temperature(10 ℃)-dry wet cycle double conditions,there exist physical chemical erosion and erosion, but the physical erosion; by reducing the water cement ratio or sulfate resistant Portland cement can significantly improve the sulfate resistance of mortar;in different water cement ratio, complex admixture and silica fume will get different results in low water ash can improve the sulfate resistance ratio, high water cement ratio will reduce the resistance to sulfate erosion.关键词
