【摘要】 本试验采用优质粉煤灰作为活性矿物掺合料代替等量水泥,通过低水灰比,成功研制出C90级高强混凝土,其流动性大,坍落度损失小,早期强度高,适合于高层建筑施工。更多还原

【Abstract】 C90 high-strength concrete may be manufactured by adopting good powder of coal ash as admixture agent of mineral and using small percentage of water cement ration. This kind of concrete enjoys the following merits such as early extra strong in strength, high fluidity in workability and small percentage loss of slump and it adapts for the construction of high-rise buildings更多还原
