组成及配合比参数对自密实混凝土抗压强度的影响研究

Effects of the composed materials and mixture parameters on the compressive strength of SCC

试验研究了水胶比、胶凝材料用量、粉煤灰掺量、骨料体积含量、粗骨料品种等配合比主要参数对自密实混凝土的抗压强度的影响,分析了自密实混凝土的抗压强度与组成材料之间的关系,建立了掺粉煤灰自密实混凝土的抗压强度公式,并对该公式进行了试验验证。

The effects of water to binder ratio, binder content, FA content, aggregate volume content, coarse aggregate kind on the compressive strength of SCC were investigated in detail.The relationship between the strength and the composed materials was established, and strength formula of SCC with FA was founded.The experiments proved the efficiency of the formula.
