Hollow floor slabs are one of the sustainable products in architecture. Compared with ordinary cast-in-place reinforced slabs, the concrete consumption of hollow floor slabs can be reduced by 45%, and the prestressed steel consumption can be reduced by 30%. Due to its hollow structure, hollow floor slabs have good sound insulation performance and can form a thermal insulation system for buildings, reducing energy consumption.

Concrete prefabricated components are mechanized concrete products, and the production equipment technology for prefabricated concrete components is currently one of the trends in construction industrialization. The corresponding traditional cast-in-place concrete has more advantages. Widely used in fields such as construction, transportation, water conservancy, high-speed rail, road construction, etc.
