水工建筑物对所使用的混凝土的技术要求很高,除了要求强度符合设计需要以外,耐久性尤为重耍,要求混凝土更加密实,具有抵抗风化、化学性腐蚀及机械力等性能。加气混凝土正是具有这些性能。在淮河佛子岭、梅山等水库,及我会在长江下游兴修的凤凰颈、白荡、梳装台等闸都使用过加气混凝土,取得了显著的成绩。汉江下游分洪杜家台闸是一项永久性的水利工程,6万多公方混凝土全部采用了加气混凝土。
Hydraulic structures are highly technical for the concrete used. Durability is of particular importance in addition to the required strength to meet the design requirements. Concrete is required to be denser and resistant to weathering, chemical corrosion and mechanical forces. Aerated concrete is precisely these properties. Fuji Ridge in the Huaihe River, Meishan and other reservoirs, and I will be built in the lower reaches of the Yangtze River Phoenix necklace, white swing, comb loading station gates have used aerated concrete, and achieved remarkable results. The flood diversion downstream of the Hanjiang River is a permanent water conservancy project. More than 60,000 square-foot concrete are all made of aerated concrete.
