摘要
以两种细骨料(机制砂、天然砂)与两种粗骨料(石灰岩碎石、花岗岩碎石)分别组合配置的4组高强混凝土为研究对象,进行了混凝土徐变性能对比试验研究。分析了细骨料和粗骨料对高强混凝土徐变性能的影响规律,提出了徐变系数的预测计算公式。
Based on the comparatively experimental study on four groups of high-strength concretes made of different combinations of two fine aggregates （machine-made and natural sands） and two coarse aggregates （crushed limestone and granite）, the effects of the fine and coarse aggregates on the creep of high-strength concrete are analyzed. The formula is proposed for predicting the creep-coefficients of high-strength concrete of different aggregates.
