预制混凝土质量控制和混凝土强度评定方法选择

Selection on Quality Control and Strength Evaluation Method of Precast Concrete

根据工程要求、组成材料的质量,施工方法等因素,介绍混凝土配合比的选择。同时还须符合合理使用材料和节约水泥等经济原则,保证预制混凝土的质量,可满足抗冻性和抗渗性等要求。

Based on the engineering requirements,material quality and construction method,selection of concrete mix proportion are introduced.The economic principles may be accorded with reasonable using material and saving cement.Thus,quality of precast concrete is ensured to meet the requirements of frost resistance and impermeability.
