摘要
本文结合河南地区地材情况,通过对原材料优选和优化配比,采用基于优质磨细矿粉、粉煤灰、硅灰的复合矿物掺合料和高效减水剂,成功配制C90级高强混凝土。具有高流动性,坍落度损失小,早期强度高的特点,适合于高层、大跨、重载现代建筑结构。
Based on the optimization of raw material with optimizing proportion, adopting good powder of fine grinding slag, fly ash and silica fume as compound mineral admixture with high performance water reducing agent, using small percentage of water cement ration, C90 high-strength concrete may be manufactured successfully. It enjoys the following merits such as high fluidity in workability, small percentage loss of slump and early strength, and it adapts for the construction of high-rise, big-span and over loading buildings.
