Anhui Concrete Prefabricated Houses

Anhui has made remarkable progress in the field of concrete prefabricated houses, with advanced technology and strong policy support.

I. Outstanding Technological Advantages and Excellent Product Performance Anhui Huiliao New Decorative Materials Co., Ltd. is a representative enterprise in this field, and its research and development of ultra-high-strength concrete (UHPC) prefabricated building wall panels have demonstrated significant technological breakthroughs. These wall panels have three core advantages:

1. Lightweight and High Strength: Each square meter weighs only 120 to 150 kilograms, just one-fourth of that of traditional wall panels, but its compressive strength exceeds 130MPa, more than four times that of ordinary concrete. This characteristic significantly reduces the building's self-weight, enhances structural safety, and simultaneously reduces transportation and installation costs.
2. Durability and Low Carbon Footprint: The water absorption rate is less than 1%, and the designed service life reaches 70 to 100 years, far exceeding that of traditional building materials. Its production process adopts low-carbon technology, aligning with the trend of green building development and helping to reduce carbon emissions throughout the building's lifecycle.
3. Integrated Design: The wall panels integrate decorative, thermal insulation, and structural functions into one, with synchronized lifespans, avoiding maintenance issues caused by the lifespan differences of different materials in traditional buildings. This design promotes the development of prefabricated buildings towards modularization and intelligence, improving construction efficiency and building quality.

II. Concurrent Policy Support and Industrial Standardization Hefei City has demonstrated standardized management of the industry by releasing the 2024 update on the collection of production information for prefabricated concrete components in prefabricated buildings. The grading system, which includes 5 A-grade enterprises, 23 B-grade enterprises, and 2 C-grade enterprises, not only incentivizes enterprises to improve their technological levels but also provides transparent selection criteria for the market. The guiding role of policies is significant, promoting the coordinated development of the upstream and downstream of the industrial chain, including the standardization and scaling of raw material supply, component production, and construction installation.

III. Broad Application Prospects and Promotion of Building Industrialization The technology of concrete prefabricated houses, through factory production and on-site assembly, significantly shortens the construction period, reduces on-site wet operations and construction waste, and aligns with the development direction of building industrialization. Driven by technological accumulation and policy support, Anhui is gradually becoming an important base for prefabricated buildings nationwide, and its experience can serve as a reference for other regions, helping the industry transform towards efficiency, environmental protection, and sustainability.
