Concrete with copper smelting slag powder as admixture and preparation method thereof
The invention discloses concrete with copper smelting slag powder as an admixture and a preparation method thereof.The concrete comprises graphene oxide modified copper slag powder and cement mortar, the mixing amount of the copper slag powder in the graphene oxide modified copper slag powder is 10% of the mass of cement, and the parameter of graphene oxide does not exceed 0.8% of the total mass of the concrete. According to the concrete with the copper smelting slag powder as the admixture, under the condition that the doping amount of the copper slag powder does not exceed 10%, the tensile strength and the compressive strength of the concrete are maintained at a high level by controlling the adding amount of the graphene oxide, and sodium lignin sulfonate is further added to serve as a water reducing agent, so that the concrete has the advantages of being high in strength and good in durability. The tensile strength and the compressive strength of the concrete are further improved.
本发明公开了一种铜冶炼渣粉做掺合料的混凝土及其制备方法，其中，混凝土包括氧化石墨烯改性的铜渣粉和水泥砂浆，其中氧化石墨烯改性的铜渣粉中铜渣粉掺量为水泥质量的10％，氧化石墨烯参量不超过混凝土总质量的0.8％。本申请的铜冶炼渣粉做掺合料的混凝土，在铜渣粉掺量不超过10％的条件下，通过控制氧化石墨烯的添加量，使得混凝土的抗拉强度及抗压强度维持在一个较高的水平，且进一步通过添加木质素磺酸钠作为减水剂的，起到对混凝土的抗拉强度及抗压强度进一步提升作用。
