低温对水泥混凝土质量的影响及控制措施

水泥混凝土浇筑时的混凝土温度、模板温度、大气温度、相对湿度以及风速等对混凝土的浇筑、振实、饰面及长期使用性能影响较大。低温条件对早期混凝土质量的影响不可忽视。在总结低温条件对混凝土质量影响的基础上,认为控制混凝土的浇筑温度和浇筑后数日的养护温度对混凝土的长期性能至关重要。本文主要对控制混凝土浇筑时的各种措施作了详细介绍。

Influence of Low Temperature to Cement Concrete and Control Measures

When pouring concrete,the concrete temperature,template temperature,air temperature,relative humidity and wind speed has a big impact on the concrete pouring,tap,facing and long-term performance.The influence of low-temperature conditions on the quality of early concrete can not be ignored.On the basis of conclusion of low temperature's effects on concrete quality,control pouring temperature and curing temperature a few days after pouring is critical for long-term performance of concrete.In this paper,the c...
