Prefabricated House Cement

Prefabricated cement houses are assembled buildings formed by factory-prefabricated components and on-site assembly, using C30-C40 grade concrete as the core material. They are efficient, economical, and environmentally friendly, suitable for temporary housing, rural self-built houses, and other scenarios.

Core Process and Materials

Prefabricated cement houses adopt an assembled reinforced concrete full-frame shear wall structure. Core components (walls, floors, beams, and columns) are cast in one piece in the factory using high-precision molds. Each module integrates a steel reinforcement skeleton (Φ8-Φ12 steel mesh), insulation layer (EPS slots), waterproof layer, and pre-embedded pipelines, forming a “building block” structure. The concrete grade is C30-C40, with a compressive strength of 25-30MPa, 1.5 times that of traditional brick-concrete structures. Modules are connected using prestressed bolts + welded steel plates, achieving a wind resistance rating of Level 10 and a seismic fortification intensity of 7 degrees (capable of withstanding damage equivalent to the Wenchuan earthquake).

Advantage Analysis

1. High Efficiency: A single 30㎡ module takes only 7 days to prefabricate in the factory, and 3 workers with a crane can complete the installation of a single module in 4 hours on-site. A 100㎡ house can be fully assembled in just 2 days.
2. Low Cost: For a 120㎡ rural self-built house, the cost of a traditional brick-concrete 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 a rental model is chosen, 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 of offcuts, with no dust or sewage discharge on-site. 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 (national standard: 0.1mg/m³), enabling “immediate occupancy.”
4. Flexible Space: Standard module dimensions are 6m×3m×3m, allowing free combination of floor plans through horizontal splicing or vertical stacking (up to 3 floors), meeting diverse needs such as rural self-built houses and cultural tourism homestays.

Limitations and Improvement Suggestions

Prefabricated cement houses have a relatively monotonous appearance. For long-term occupancy, soundproof cotton and insulation boards should be added, and special attention should be paid to waterproofing at roof joints. Suitable scenarios include temporary construction site housing, rural self-built houses, and cultural tourism homestays. In Sichuan, the cost of the main structure for a 200㎡ reinforced concrete prefabricated house can be as low as 110,000 yuan. Mainstream brands in the market include Xinwei Hongtu, Dingshun, and Xinsheng.
