| 摘 要： | 再生混凝土在环保和可持续发展方面的优势使其日益成为重要的建筑材料。本文对再生混凝土的抗冻性能做了基础试验研究,探讨了再生混凝土实际应用的可能性。快速冻融试验发现,再生混凝土的强度、质量和相对动弹模量均不同程度的下降,其质量和相对动弹模量下降幅度小于普通混凝土,而强度下降幅度大于普通混凝土。

| Abstract: | Recycled aggregate concrete is gradually formed into important building materials on environment protection and sustainable development.Basic experimental research in frost resistance was carried out,and discussed practical possibility on engineering application.It was concluded that strength,mass,and relative dynamic modulus all decreased in different levels,and argument fall of mass and relative dynamic modulus in recycled aggregate was less than common concrete,where,argument fall of strength was higher than common concrete. |
