High-performance modified recycled concrete and preparation method thereof
The invention relates to the technical field of concrete preparation, in particular to high-performance modified recycled concrete and a preparation method thereof. The high-performance modified recycled concrete is prepared from water, an efficient concrete admixture, calcined diatomite, cement, fly ash, recycled coarse aggregate, natural coarse aggregate and sand. According to the method, the calcined diatomite is soaked in advance and then is mixed and stirred with other raw materials, so that the phenomena of workability reduction caused by the agglomeration effect of the calcined diatomite, strength dispersion caused by non-uniform cement-based reaction and the like are reduced; the calcined diatomite has strong adsorption effect and micro-aggregate effect, so that the high-performance modified recycled concrete prepared by the invention has the advantages of high strength, low permeability, high freezing resistance and the like.
本发明涉及混凝土制备技术领域，具体为一种高性能改性再生混凝土及其制备方法。采用水、高效混凝土外加剂、煅烧硅藻土、水泥、粉煤灰、再生粗骨料、天然粗骨料、砂，来制备高性能改性再生混凝土；本发明采用煅烧硅藻土预先浸泡后，再与其他原料混合搅拌的方法，降低了因煅烧硅藻土团聚效应造成的和易性下降及水泥基反应不均匀造成的强度离散等现象；由于煅烧硅藻土具有很强的吸附作用和微集料效应，使得本发明制备的高性能改性再生混凝土，具有高强度、低渗透和高抗冻等优点。
