[Video] Has It Been a Dangerous House for Only Ten Years? Long Shell on Concrete, Suspected of Building House with Sea Sand

Recently, the owners of Mingshi Haoyuan Community in Shishi City, Quanzhou, Fujian, told reporters that their community had become a dangerous house in less than 15 years, which was due to the incorporation of sea sand construction.

Sea sand contains a certain amount of chlorine salt, which can corrode the steel bars in concrete structures, thereby reducing the durability of concrete structures and even causing the collapse of houses.
