摘要
再生骨料本身缺陷及加工过程复杂导致再生混凝土强度不高,工程推广受到限制。通过比较天然混凝土与再生混凝土抗压强度的区别,利用化学处理以及加入活性掺合料对再生混凝土进行表面改性,并提出提高再生混凝土强度的途径。
The low compressive strength of recycled concrete led by itself defects of the recycled aggregate and working process, its application in engineering is limited. Comparing the difference between the compressive strength of recycled concrete and natural concrete, chemical treatment and active mixtures were used for recycled concrete to improve its surface modification, and the measures to improve strength of recycled concrete were also proposed.
