Reinforced treatment method for waste concrete recycled aggregate
The invention discloses a reinforcing method of waste concrete recycled aggregate, and relates to the technical field of building materials, and the reinforcing method comprises the following steps: washing the crushed and screened waste concrete recycled aggregate with the particle size of 5-40mm with tap water, and naturally airing. According to the method, tap water with low pressure intensity is used for flushing the recycled aggregate, impurities are removed, more capillary pores are opened, then dilute acetic acid and a water tank with vibration are used for strengthening the recycled aggregate, physical and chemical modes interact, the reaction efficiency of acetic acid and mortar on the surface of the recycled aggregate is improved, and the recycling effect of the recycled aggregate is improved. And various properties of the recycled aggregate are effectively improved. Tap water, waste liquid and waste residues used in the strengthening process can be reutilized to be used in preparation of regenerated products, and compared with an existing regenerated aggregate strengthening method, the method is safe and high in strengthening efficiency, various basic performance of the regenerated aggregate can be effectively improved, the application range of the regenerated aggregate is widened, and no waste is generated in the whole process.
本发明公开了一种废弃混凝土再生骨料的强化方法，涉及建筑材料技术领域，强化方法包括以下步骤：将经破碎、筛分后的粒径为5‑40mm的废弃混凝土再生骨料采用自来水冲洗，并自然晾干。本发明先利用压强较低的自来水对再生骨料进行冲洗，去除杂质，开放更多毛细孔，再利用稀醋酸以及带震动的水槽对再生骨料进行强化处理，物理和化学方式相互作用，提高醋酸与再生骨料表面砂浆反应效率，有效提高了再生骨料的各项性能。强化过程中所利用到的自来水，废液，废渣均可二次利用于再生制品的制备中，与现有的再生骨料强化方法相比，该方法安全，强化效率高，能有效提高再生骨料各项基本性能，拓宽其应用范围，且整个过程无废物产生。
