“双掺”泵送混凝土配合比项目优化研究

The application of limestone powder as admixtures in concrete

针对当前"双掺"泵送混凝土配合比项目优化研究存在的问题,以泵送混凝土强度等级C30为例,进行配合比双掺技术研究。从技术方案及主要操作流程、混凝土的试验分析和社会及经济效益等方面详细阐述了"双掺"泵送混凝土配合比项目优化研究的过程,供相关人员参考借鉴。

In this paper, the existing problems in the optimization of concrete mixing ratio of mixed pump are presented, and the ratio of concrete strength grade C30 is studied. From a technical scheme and main operation flow, the experimental analysis and the social and economic benefits of concrete and so on several aspects in detail elaborated the double mixing project optimization study the process of pumping concrete mixture ra-tio, and serve as a reference for everyone to use.
