基础防水混凝土冬期负温施工

Constructing Waterproof Concrete of Band Cooler Foundation at Low Temprature in Winter

以鞍钢三烧改造工程中的带冷机基础混凝土的施工为例，讨论要求达到Ｓ８抗渗标号的冬期负温施工问题。分析此种混凝土的防冻机理，采取综合技术措施可获得预期效果。

Take the example of Third Sintering Manufacture of Anshan Iron and Steel Complx,where waterproof concrete of band cooler foundation was constructed at -10～-22 ℃ in winter,and was required to reach S8 antibleeding label.Ther paper analyizes the coldproof and antibleeding of this kind of concrete,and the anticipative results with the combination methods.
