摘要
结合太原市某工程用C80钢管混凝土施工用混凝土配合比设计研究,进行了减水剂、水胶比、胶凝材料用量、砂率等配合比参数对混凝土工作性影响的试验研究,试验结果表明,适宜的配合比参数可以制备出具有自密实性能的C80混凝土。
In this paper, combined with the study on mix proportion＇design of C80 concrete-filled steel tube for eonstruction in Taiyuan City, the effects of water-reducing agent, water-cement ratio, and amount of cementing material and sand ratio on the working efficiency of concrete are studied. The experimental results show that the C80 concrete with self-compacting property can be prepared by proper mixing ratio.
