National Cement Prefabricated Houses

National cement prefabricated houses are built using a prefabricated reinforced concrete full-frame shear wall structure, constructed through factory prefabrication and on-site assembly. They are becoming a popular choice for rural self-built houses, commercial spaces, and cultural tourism projects.

Core Process and Structural Features
The core process of cement prefabricated houses is "factory prefabrication + on-site assembly." At specialized production bases, high-precision molds are used to cast core components such as walls, floors, and beams in one go. Each module integrates multiple structures, including a steel reinforcement framework, insulation layers, waterproofing layers, and pre-embedded piping, forming flexible "building blocks." The standard module size is 6m × 3m × 3m (length × width × height), allowing for free户型 (floor plan) customization through horizontal splicing and vertical stacking (up to 3 floors), suitable for various scenarios.

Main Advantages

1. High Efficiency: A single 30㎡ module takes only 7 days for factory prefabrication. During on-site installation, three workers with a crane can complete a single module installation in 4 hours, and the overall construction of a 100㎡ house takes only 2 days.
2. Low Cost: For a 120㎡ rural self-built house, the cost of a traditional brick-and-mortar structure is approximately 180,000-220,000 yuan, while the cost of the main modules for a cement house is only 120,000-150,000 yuan, reducing the overall cost by 30%. If choosing a leasing model, the annual rent can be as low as 5,000 yuan per room.
3. Green and Environmentally Friendly: Factory production achieves a 95% recycling rate for offcuts, with no dust or sewage emissions at the construction site, and construction waste is only 10% of that from traditional construction. Environmentally friendly concrete and water-based paints are used, with formaldehyde emissions ≤ 0.05mg/m³, well below the national standard (0.1mg/m³), enabling "immediate occupancy."
4. Good Performance: Using C30-C40 grade concrete with built-in Φ8-Φ12 steel reinforcement mesh, the compressive strength reaches 25-30MPa, 1.5 times that of traditional brick-and-mortar structures. The walls have pre-reserved slots for EPS insulation layers, improving thermal insulation by 40%. Modules are connected using pre-stressed bolts and welded steel plates, with a wind resistance rating of 10 and a seismic fortification intensity of 7 degrees.
5. Flexible Space: Standardized module sizes allow for free户型 (floor plan) customization through combinations, suitable for rural self-built houses, cultural tourism homestays, and other scenarios.

Application Scenarios
In Qinghai's high-altitude, hypoxic, and ecologically fragile areas, cement prefabricated houses have been applied in ecological protection, cultural tourism experiences, and industrial upgrading, becoming a typical case of transitioning from "pilot projects" to a "systemic" approach.
