摘　　要：通过高强复合骨料混凝土和基准高强混凝土的对比试验表明,复合骨料混凝土的自收缩能显著降低。尤其对于含硅灰或矿粉的混凝土,复合骨料降低混凝土的自收缩效果更好。Through comparative test with reference concrete, the auto-shrinkage of concrete with composite aggregate can reduced significantly. For concrete containing silica fume or ground slag, the reduction of auto-shrinkage is more effective by composite aggregate. The measuring instrument of concrete auto-shrinkage is designed by oneself.
