Low-alkalinity green seawater sea sand concrete and preparation method thereof
The invention provides low-alkalinity green seawater sea sand concrete and a preparation method thereof, and relates to the technical field of cement-based composite materials. The low-alkalinity green seawater-sea sand concrete provided by the invention is prepared from the following raw materials: a cementing material, sea sand, gravel, seawater and a water reducing agent, the mass ratio of the cementing material to the sea sand to the gravel to the seawater to the water reducing agent is 1: (0.9-1.1): (2.2-2.7): (0.35-0.45): (0-0.05); the cementing material comprises cement, calcined engineering residue soil and silica fume. The concrete provided by the invention has low alkalinity and good mechanical properties, and can be applied to engineering as low-alkalinity concrete. Compared with traditional low-alkali concrete, the low-alkali concrete has the advantages that a large amount of mineral admixtures do not need to be doped, the large mixing amount of the engineering muck is adopted, meanwhile, a small amount of silica fume is doped, the cost of the concrete is reduced, meanwhile, resource utilization of the engineering muck is achieved, and the low-alkali concrete is suitable for application and popularization.
本发明提供了一种低碱性绿色海水海砂混凝土及其制备方法，涉及水泥基复合材料技术领域。本发明提供的低碱性绿色海水海砂混凝土，包括以下制备原料：胶凝材料、海砂、碎石、海水和减水剂；所述胶凝材料、海砂、碎石、海水和减水剂的质量比为1：0.9～1.1：2.2～2.7：0.35～0.45：0～0.05；所述胶凝材料包括水泥、煅烧后工程渣土和硅灰。本发明提供的混凝土具有较低的碱性和良好的力学性能，可作为一种低碱度混凝土应用于工程中。本发明相较于传统低碱混凝土，无需掺入大量矿物掺合料，而是采用工程渣土的大掺量，并同时掺入少量的硅灰，降低了混凝土的成本，同时实现了工程渣土的资源化利用，适宜推广应用。
