摘要
依托某新建水泥路面工程,采用正交试验,分析了水胶比、粉煤灰用量、凝胶材料总量三个因素对水泥-粉煤灰混凝土性能的影响。指出粉煤灰用量能显著影响水泥混凝土的早期强度,而水胶比在后期能够显著影响水泥混凝土强度。
Based on a new concrete road, with orthogonal test, the influence of the water-cement ratio, the amount of fly ash and total gel materials on cement concrete that in early stage, the amount of/fly ash can significantly affect the but water-cement ratio can significantly affect it in the latter. are analyzed. It is found cement concrete strength
