文章对再生混凝土抗压强度、劈裂强度、抗折强度等基本力学指标及这些指标随龄期的变化情况进行了研究，还研究了再生混凝土的峰值应变、弹性摸量及应力-应变曲线。再生混凝土试件中粗骨料替代率均为100％。试验结果表明，各种规范给出的各种力学指标间的换算关系，多数情况下已不适用于再生混凝土；通过回归分析得到了适合再生混凝土各指标间换算的公式。
文章對再生混凝土抗壓彊度、劈裂彊度、抗摺彊度等基本力學指標及這些指標隨齡期的變化情況進行瞭研究，還研究瞭再生混凝土的峰值應變、彈性摸量及應力-應變麯線。再生混凝土試件中粗骨料替代率均為100％。試驗結果錶明，各種規範給齣的各種力學指標間的換算關繫，多數情況下已不適用于再生混凝土；通過迴歸分析得到瞭適閤再生混凝土各指標間換算的公式。

The basic mechanic indices of recycled aggregate concrete (RAC) such as compressive strength ,split strength ,flexural strength were investigated and so were the changes of these indices at early age .The peak strain ,elastic modulus and stress-strain curve of RAC were also studied .In RAC specimens ,coarse aggre-gates were replaced by recycled aggregates with a replacement rate of 100% .The results indicated that the conversion formulas for different mechanic indices were not suitable for RAC in most cases .New conversion formulas for RAC were presented by fitting experimental data .
