No.
The state prohibits the use of sea sand for the construction of roads, bridges, military, civil, commercial housing and public **** facilities, because sea sand contains natural salts that are highly corrosive. Cement mixed with sea sand will rust away the steel bars in less than 5 years.
Using sea sand to mix concrete and pour the building, the steel reinforcement in the concrete will be slowly corroded and oxidized by the salt penetrated from the sea sand, resulting in a decrease in prestressing force and a decrease in strength, hardness and bearing capacity, which will seriously affect the service life of the building.
Walls and floors painted with sea sand will be seriously damp, and when encountering southeast wind or rainy season, the walls will ooze out a large number of water droplets and water droplets, and living in such a house for a long period of time will bring joint pain to the human body. In addition, the salt in the sea sand can not be rinsed off no matter how it is soaked.
