10℃下不同水灰比水泥基材料抗硫酸盐侵蚀性能试验研究
Sulfate Resistance of Cement Based Material with Different Water-Cement Ratio at 10 ℃
摘要
Abstract
The effects of different water-cement ratio cement mortar samples against sulfate attack at 10℃were studied .Ordinary portland cement , medium sulfur-resistant cement and slag with silica fume cement mortar samples were prepared with cement ratio of 0 .36 and 0 .5 .Mortar samples were stored in 3％Na2SO4 sulfate solution at ( 10 ±1 ) ℃, and their strength developments were measured .Sulfate resistance of mortar samples was evaluated by considering the mortar strength and corrosion resistance . The results show that, at 10 ℃, the strength of 0.36 water-cement ratio mortar is higher than 0.5 water-cement ratio, and the sulfate resistance increases with the decrease of water-cement ratio.The addition of mineral admixture improves the sulfate resistance , and the better the sulfate resistance , the more the addition of silica fume .The mortar resistance to sulfate attack is 15％slag+3％silica fume>15％slag+1％silica fume>medium sulfur-resistant cement>ordinary portland cement .关键词
