摘要
再生骨料表面存在的附着砂浆和破碎产生的微裂缝致使其在混凝土中的应用受到限制。目前再生骨料强化主要是通过去除附着砂浆或改性强化附着砂浆来改善再生骨料的性能,结合近年来改性强化再生骨料的技术与方法,综述了各种方法的强化机理和强化效果,并提出了研究建议。
The application of recycled aggregate in concrete is limited due to the adhesion mortar on the surface and micro-cracks caused by breakage.At present, the performance of reclaimed aggregate is improved by removing attached mortar or modifying attached mortar.In this paper, combined with the techniques and methods of strengthening reclaimed aggregate modified in recent years, the strengthening mechanism and effect of various methods were reviewed, and research suggestions were put forward.
