摘要
建筑垃圾的主要回收途径是作为再生骨料用于再生混凝土制备,然而,相比于天然骨料,再生骨料存在强度低、孔隙率高、吸水性高、形状不规整等缺点。骨料是混凝土的主要受力骨架,当骨料强度不足时,材料力学性能无法被充分利用,为更明确混凝土工作性能和破坏机理,对再生骨料损伤机理展开研究。针对再生骨料缺陷进行强化,梳理分析已有研究,总结强化方式对内部骨料损伤影响,有利于今后再生骨料的应用。
The main recycling way of construction waste is used as a recycled aggregate for the preparation of recycled concrete.However,compared with the natural aggregate,the recycled aggregate has some disadvantages,such as low strength,high porosity,high water absorption and irregular shape.Aggregate is the main stressed skeleton of concrete.When the aggregate strength is insufficient,the mechanical properties of the material cannot be fully utilized.In order to more clarify the working performance and damage mechanism of concrete,the damage mechanism of recycled aggregate is studied.For the regenerated aggregate defects of the reinforcement,combing and analysis have been studied,summarizing the impact of the reinforcement method on the internal aggregate damage.It is beneficial to the application of reclaimed aggregate.
