南水北调中线工程耐久性混凝土配合比试验

Mix Proportion Test of Durable Concrete of South-to-North Water Diversion Middle Route Project

南水北调中线引汉总干渠工程线路长,环境较为恶劣,混凝土结构耐久性问题突出。立足于工程沿线既有建筑材料,开展了原材料性能指标测试、混凝土试配以及耐久性能检测等,配制出了工作性能优异、耐久性能好的C30W6F150二级配普通混凝土,并提出了相应的施工质量控制措施。

The main channel from Hanjiang River of South-to-North Water Diversion Middle Route Project has a long distance,and adverse circumstance.The problem of concrete durability is prominent.Based on the material characters of local work site area,the performance index test of raw materials,concrete mix proportion test,and concrete durability test are carried out.Through these test works,durable concrete C30W6F150 with excellent work performance is obtained,and the corresponding measures of construction quality control are suggested.
