本文针对C30及以下低强度等级混凝土配合比设计并改进,限制最大胶凝材料用量,尤其是水泥用量,复掺活性矿物掺合料,掺入高性能减水剂提高混凝土拌合物流动性能,并复合粘度调节剂起到增加混凝土拌合物粘稠度的作用,确保混凝土拌合物粘聚性、包裹性良好,不泌水、不离析,从而配制智能动力混凝土,实现混凝土低强度自密实。
In this paper, we design and improve the mixture ratio of C30 and below low strength concrete to limit the maximum amount of cementitious materials, especially the amount of cement, complex mixed mineral admixtures, doping high performance water reducing agent to improve the flow properties of concrete mixture, And the compound viscosity modifier plays the role of increasing the viscosity of the concrete mixture to ensure that the concrete mixture has good cohesiveness and good encapsulation without bleeding and isolating so as to formulate the intelligent dynamic concrete and realize the low-density self-compacting of the concrete .
