| 摘 要： | 复合掺加粉煤灰和矿渣微粉两种超细掺合料的目的是充分利用它们的优良品质和特点,在混凝土中产生优势互补,减小负面影响作用。试验采用大掺量超细掺合料配制高强泵送混凝土,探究复合粉掺量变化以及粉煤灰和矿渣微粉组分比例不同对强度的影响。结果表明,粉煤灰混凝土早期强度低后期强度高,矿渣微粉混凝土早期强度发展迅速,而两者复掺对混凝土早期和后期强度增长明显。

| Abstract: | This study was aimed at preparing the superfine admixture with fly ash and slag micro powder to sufficiently use their fine quality and characteristics to develop their sufficient complementary and reduce the negative effect.In this experiment,the high strength pumping concretes were prepared with superfine admixture to discuss the change law of combined admixtures quantity and the effect of different ratio of fly ash to slag micro powder on strength development.Result indicated that the strength of fly ash... |
