High-durability recycled concrete and preparation process of recycled structural concrete
The invention relates to high-durability recycled concrete and a preparation process of recycled structural concrete, and belongs to the field of concrete. The preparation process comprises the following steps: preparing a recycled aggregate: removing reinforcing steel bars of concrete blocks and primarily crushing to obtain aggregate particles; and carrying out preliminary screening on the aggregate particles, to obtain regenerated sand, carrying out accelerated rusting, secondary crushing and screening on fragments obtained through screening, then carrying out acid pickling, alkali washing and carbonization strengthening treatment, to obtain regenerated broken stone; preparing the recycled concrete: stirring and mixing recycled broken stone, recycled sand and cement slurry, to obtain the recycled concrete; and preparing the regenerated structural concrete: building a template, bundling steel bars in the template, pouring the regenerated concrete into the template, and curing to obtain the regenerated structural concrete. The preparation process of the recycled structure concrete is simple, the prepared recycled concrete has the characteristics of excellent mechanical property, freezing resistance and steel bar corrosion resistance, and building waste is well recycled.
本申请涉及一种高耐久的再生混凝土以及再生结构混凝土的制备工艺，属于混凝土领域。其制备工艺包括以下步骤：制作再生骨料：去除混凝土块的钢筋并初步破碎，获得骨料颗粒；将骨料颗粒进行初步筛分，获得再生砂子，对筛分获得的碎块进行加速锈化、二次破碎并筛分，再经过酸洗、碱洗、碳化加强处理，获得再生碎石；制作再生混凝土：将再生碎石、再生砂子与水泥浆料搅拌混合，获得再生混凝土；制作再生结构混凝土：搭建模板，在模板中捆扎钢筋，往模板中浇筑再生混凝土，养护后获得再生结构混凝土。本申请的再生结构混凝土制备工艺简单，制得的再生混凝土具有力学性能、抗冻性以及耐钢筋腐蚀性能优异的特点，使建筑废料得到良好的资源回收再利用。
