Abstract | 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 |
