Lightweight Aggregates Used for Concrete

High Efficiency Cooling and Refrigeration Coating

Lightweight concrete has long been used for suspended floors in order to reduce the weight on the structure and to increase the fire rating. And since a lightweight floor is typically thinner (5.25 inches versus 6.5 inches with normal weight for the equivalent fire rating), a lightweight floor will be 40% to 45% lighter than a normal-weight floor. So while lightweight concrete does cost a little more, with the reduction in weight, the building frame costs less. But lightweight concrete has other advantages when designed to take advantage of internal curing.

Through bionic design,  "lotus leaf effect" can be achieved on the surface of the coating perfectly, and the dust on the surface can be taken away by gravity under the erosion of rain to achieve self-cleaning effect. It is suitable for the coating of ordinary buildings, external walls of super high-rise buildings or prefabricated components.
