Finished Cement Prefabricated House

A finished cement prefabricated house is an assembled house built with prefabricated reinforced concrete modules as its core, combining factory prefabrication with on-site assembly. Its core processes, performance advantages, and economic benefits are as follows:

1. Production Process and Structural Features
At specialized production bases, core components such as walls, floor slabs, and beams are cast in one piece using high-precision molds. Each module integrates a steel reinforcement framework, insulation layer, waterproof layer, and pre-embedded piping systems, forming standardized 'building blocks'. 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. Walls are designed with EPS insulation layer slots for on-site insertion, improving thermal insulation by 40% and achieving warmth in winter and coolness in summer. Modules are connected via pre-stressed bolts and welded steel plates to form an integrated framework, withstanding wind speeds up to Category 10 and seismic intensity of 7 degrees (capable of withstanding the destructive force of the Wenchuan earthquake).

2. Economic and Efficiency Advantages
Taking a 120㎡ rural self-built 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 cement house modules is only 120,000-150,000 yuan. Including interior and exterior decoration, the total cost can be controlled within 200,000 yuan, reducing overall costs by 30%. The construction period is significantly shortened: a single 30㎡ module takes only 7 days for factory prefabrication. After transportation to the site, 3 workers with a crane can complete the installation of a single module in 4 hours, with the entire 100㎡ house taking only 2 days to assemble. A case study in the Foshan area shows that a cement prefabricated house can be assembled into a villa in 4 hours, with a price of approximately 300 yuan per square meter and a warranty period of up to 70 years.

3. Applicable Scenarios and Limitations
It is suitable for scenarios with high requirements for construction efficiency, cost, and seismic performance, such as rural self-built houses, temporary buildings, or post-disaster reconstruction projects. Its standardized design facilitates rapid replication, but the modular nature may limit the personalization of architectural styling. Additionally, transportation distance significantly impacts costs, requiring a comprehensive assessment of economic viability based on the factory's coverage area.
