摘　　要：以2种细骨料(机制砂、天然砂)与2种粗骨料(石灰岩碎石、花岗岩碎石)分别组合配制4组高强混凝土为研究对象,进行混凝土自收缩性能对比试验研究。分析细骨料和粗骨料对高强混凝土自收缩性能的影响规律,并提出自收缩变形的预测计算公式。Based on the comparatively experimental study on four groups of high-strength concrete made of different combinations of two fine aggregates（machine-made and natural sand） and two coarse aggregates （crushed limestone and granite）, concrete are analyzed. the effects of the fine and coarse aggregates on the autogenous shrinkage of high-strength The formulas are proposed for predicting the autogenous shrinkage of high-strength concrete of different aggregates.

关 键 词：高强混凝土 自收缩 骨料 试验研究
