Cement Prefabricated House in Zhanjiang
In Zhanjiang, cement prefabricated houses have high cost-effectiveness and market attention, with advantages reflected in efficiency, cost, environmental protection, and performance.
I. Significant Efficiency Advantages
Cement prefabricated houses adopt a combined model of factory prefabrication and on-site assembly. A single 30㎡ module can be prefabricated in the factory in just 7 days. After being transported to the site, with the cooperation of 3 workers and a crane, a single module can be installed in 4 hours. Taking a 100㎡ house as an example, the overall construction only takes 2 days, which is much faster than the construction cycle of traditional brick-and-mortar houses. This can significantly shorten the construction time and reduce labor input.
II. Outstanding Cost Advantages
Taking a 120㎡ self-built rural house as an example, the cost of a traditional brick-and-mortar structure is approximately 180,000 - 220,000 yuan (including labor), while the cost of the main modules of a cement house is only 120,000 - 150,000 yuan. With interior and exterior decoration, the total cost can be controlled within 200,000 yuan, reducing the overall cost by about 30%. If the rental model is chosen, the annual rent can be as low as 5,000 yuan per room, further reducing the initial investment cost and being suitable for users with limited budgets.
III. Green and Environmentally Friendly Characteristics
Factory production is fully controllable, with a scrap recovery rate of 95%. There is no dust or sewage discharge at the construction site, and the construction waste is only 10% of that of traditional house construction. Environmentally friendly concrete and water-based paints are used as materials. The formaldehyde emission is ≤0.05mg/m³, which is much lower than the national standard (0.1mg/m³), meeting the requirements of green buildings and reducing environmental pollution.
IV. Excellent Performance
C30 - C40 grade concrete is used, with built-in Φ8 - Φ12 steel bar meshes. The compressive strength reaches 25 - 30MPa, which is 1.5 times that of traditional brick-and-mortar structures. The walls have reserved slots for EPS insulation layers. After on-site insertion, the thermal insulation performance is improved by 40%, providing significant warmth in winter and coolness in summer. The modules are connected through prestressed bolts + welded steel plates to form an overall framework, with a wind resistance rating of Level 10 and a seismic fortification intensity of 7 degrees (equivalent to the destructive power of the Wenchuan earthquake), ensuring high safety.
V. Well-Established Quality Assurance System
The Zhanjiang Housing and Urban-Rural Development Bureau has published a list of enterprises with ready-mixed concrete professional contracting qualifications (as of July 15, 2025). These enterprises must operate in strict accordance with national standards and laws and regulations, providing a certain guarantee for the quality of cement prefabricated houses.
