Durable recycled concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses durable recycled concrete and a preparation method thereof. The durable recycled concrete comprises the following raw materials: cement, recycled coarse aggregate, recycled fine aggregate, water, mulberry leaf powder and a water reducing agent. The preparation method comprises the following steps of S1, preparing concrete,and uniformly stirring and mixing the cement, the recycled coarse aggregate, the recycled fine aggregate, the mulberry leaf powder and the water reducing agent, adding water, and uniformly stirring toobtain the concrete. According to the durable recycled concrete disclosed by the invention, the mulberry leaf powder is added and is filled in micro cracks and pores between the recycled coarse aggregate and the recycled fine aggregate, so that the overall density of the concrete is increased, the mulberry leaf powder contains a large amount of cellulose and mineral substances, and the celluloserestrains further expansion of cracks, the stability and firmness of the internal structure of the concrete are improved, and the structural strength of the concrete is better due to the addition of minerals, so that the durability of the concrete is comprehensively improved, and the concrete is more durable.
本申请涉及混凝土领域，具体公开了一种耐用再生混凝土及其制备方法。耐用再生混凝土包括如下原料：水泥、再生粗集料、再生细集料、水、桑叶粉和减水剂；其制备方法为：S1.混凝土的制备；将水泥、再生粗集料、再生细集料、桑叶粉和减水剂搅拌混匀，再加入水搅拌均匀，制得混凝土。本申请的耐用再生混凝土中加入桑叶粉，桑叶粉填充于再生粗集料和再生细集料之间的微细裂痕和孔隙中，增加了混凝土整体的致密度，且桑叶粉中含有大量纤维素和矿物质，纤维素约束了裂缝的进一步扩展，提高了混凝土内部结构的稳定性和牢固性，矿物质的加入使得混凝土的结构强度更佳，从而综合提高了混凝土的耐久性，使得混凝土更加耐用。
