| 中文摘要: |
| 针对再生骨料由于本身结构缺陷的原因，造成混凝土力学性能和耐久性不良的问题，采用再生骨料裹浆预处理和密实骨架堆积配合比设计方法，弥补再生骨料的结构缺陷，提高混凝土密实程度，使得再生骨料混凝土的抗压强度和抗碳化性能、抗氯离子渗透性能得到有效改善。 |
| 英文摘要: |
| In view of the structural defects caused by recycled aggregates, the mechanical properties and durability of concrete are poor. The regenerative aggregate pretreatment and dense matrix stacking ratio design method are used to compensate for the structural defects of recycled aggregates and improve concrete compaction. To the extent, the compressive strength, carbonation resistance and chloride ion penetration resistance of recycled aggregate concrete are effectively improved. |
