C100高强高性能混凝土预制构件制备关键技术研究

Study on key production technologies of C100 high strength and high performance concrete prefabricated components preparation

基于Dinger-Funk紧密堆积模型进行胶凝材料颗粒级配(0.01~75μm)及骨料级配(0.15~20 mm)的计算结果,进行C100混凝土配合比验证和优化,确定了符合预期目标的C100混凝土配合比。并将其应用于足尺框架预制构件的制备,通过对原材料的选择、生产线的要求、制备工艺关键技术等方面展开研究,对制备过程中发现的问题提出了解决措施并验证,最终形成了一套相对完整的高强高性能预制构件制备工艺并积累了较为丰富的经验。

This paper introduced a calculation method of C100 high strength and high performance concrete mix proportion which is based on the Dinger-Funk dense packing model. This model contained the gradation of cementitious materials （0.01 ~75 ~Lm） and aggregate （0.15N20 ram）. After the verification and modification of calculation result, we confirmed the mix proportion and used it into the real size prefabrication concrete production. Through the research of the raw material choice,requirement of the production llne,and the key production technologies,we proposed solutions to the problems occuned in the process of production and make them verified. Through the study of this paper, we accumulated a wealth of experience and formed a relative complete product process, which is about the high strength and high performance concrete prefabricated component.
