Preparation method of mixed recycled aggregate concrete and mixed recycled aggregate concrete
The invention discloses a preparation method of mixed recycled aggregate concrete and the mixed recycled aggregate concrete. The preparation method of the mixed recycled aggregate concrete comprises the step of preparing the mixed recycled aggregate concrete from cement, mixed recycled aggregate, mixed sand, fly ash and an additive, the mixed recycled aggregate is formed by mixing recycled aggregate and primary aggregate, the mixed sand material is formed by mixing recycled fine particles and natural sand, and the mortar is prepared from the mixed sand material. The mass ratio of the recycled aggregate to the mixed recycled aggregate and the non-uniform coefficient, the grading coefficient and the void ratio of the mixed recycled aggregate are specifically limited, so that the reasonable range of the non-uniform coefficient and the grading coefficient of the mixed recycled aggregate with large stacking density and small void ratio and the corresponding filling mixed sand material are determined; therefore, the high-strength-grade mixed recycled aggregate concrete is prepared, a pouring material of a high-performance concrete structure is replaced, and the application range of the recycled aggregate concrete is greatly widened.
本申请公开了一种混合再生骨料混凝土的制备方法及混合再生骨料混凝土，混合再生骨料混凝土的制备方法包括：通过水泥、混合再生骨料、混合砂料、粉煤灰和外加剂制备而成；混合再生骨料包括再生骨料和原生骨料并混合而成，混合砂料包括再生细颗粒和天然砂并混合而成，通过混合砂料制备成砂浆。通过对再生骨料占混合再生骨料的质量比例、混合再生骨料的不均匀系数、级配系数以及空隙率进行针对性的限定，从而确定具有堆积密度大、空隙率小的混合再生骨料的不均匀系数和级配系数的合理范围，以及相应的填充混合砂料，从而制备高强度等级的混合再生骨料混凝土，代替高性能混凝土结构的浇筑材料，并大大拓宽再生骨料混凝土的应用范围。
