C25芯柱自密实混凝土的优化配制

Optimizing preparation for C25 core column self-compacting concrete

本研究利用地方原材料,在初步计算C25芯柱自密实混凝土的配合比的基础上,分析了外加剂和水胶比中单一因素对自密实混凝土性能的影响,优化出C25芯柱自密实混凝土。试验结果表明,C25芯柱自密实混凝土优化后配合比能满足其工作性和强度等级的要求,并与同强度等级Cb混凝土进行了经济比较。对混凝土小型砌块配芯柱的结构体系的发展具有重要意义。

Based on the preliminary computation of mixture ratio for C25 core column self-compacting concrete, this paper uses local material to analyze the single factor of the additives and waterbinder ratio, and to optimize the performance of self-compacting concrete and C25-core self-compacting concrete. The experimental results indicate that the C25 core column self-compacting concrete can satisfy its workability and strength, and with the same intensity level Cb concrete economic comparison, hence of great significance for the development of the small concrete-block structure with core system.
