摘要
在不同的水胶比条件下,考察了凝聚态硅灰对低工作性混凝土强度发展历程的影响。试验结果表明:在研究的水胶比范围内,凝聚态硅灰对低工作性混凝土强度的贡献主要是在后期,且随着水胶比的降低,其增强能力的发挥进一步推迟。
The effect ofdensified silica fume on low workability concretes under different water to binder ratio was studied.Experimental results show that within the water to binder rage investigated,the strengthening effect of densified silica fume on low workability concrete emerges mainly during the later age.And with the decrease of water to binder ratio,the strengthening effect of densified silica fume on low workability concrete is postponed even more.
