摘要
在用机制砂配制自密实混凝土配合比中,通过简化因素数量,使用正交试验法进行组合设计,配制出性能良好的自密实混凝土;并研究了不同石粉含量对混凝土自密实性能的影响,提出了合理的石粉含量。
In the process of mixing proportion of self-compacting concrete with manufactured sand,by simplifying the number of factors and using orthogonal test method,the self-compacting concrete with good performance was prepared.The influence of different stone powder content on concrete self-compacting performance was studied,and the reasonable stone powder content was put forward.
