Zhejiang Cement Prefabricated Houses

Zhejiang cement prefabricated houses mainly refer to prefabricated reinforced concrete houses, which are built through factory production and modular assembly with prefabricated reinforced concrete modules as the core.

Technical Principles and Core Highlights

Zhejiang cement prefabricated houses adopt a factory-prefabrication + on-site assembly model. At specialized production bases, high-precision molds are used to cast core components such as walls, floors, and beams and columns in one go. Each module integrates multiple structures including a steel reinforcement framework, insulation layers, waterproof layers, and pre-embedded pipelines. Its core technical highlights are remarkable: It uses C30 - C40 grade concrete with built-in φ8 - φ12 steel reinforcement meshes, achieving a compressive strength of 25 - 30MPa, which is 1.5 times that of traditional brick-and-concrete structures. The walls have reserved slots for EPS insulation layers, and when embedded on-site, the thermal insulation performance is improved by 40%. The modules are connected through pre-stressed bolts + welded steel plates to form an overall framework, with a wind resistance rating of up to Level 10 and a seismic fortification intensity of 7 degrees.

Advantages and Characteristics

• High efficiency: A single 30㎡ module takes only 7 days for factory prefabrication. After being transported to the site, with the cooperation of 3 workers and a crane, a single module can be installed in just 4 hours, and the overall construction of a 100㎡ house takes only 2 days.
• Low cost: Taking a 120㎡ self-built rural house as an example, the cost of a traditional brick-and-concrete structure is about 180,000 - 220,000 yuan (including labor), while the cost of the main modules of the cement house is only 120,000 - 150,000 yuan. With interior and exterior decoration, the total cost can be controlled within 200,000 yuan, representing a 30% reduction in overall cost. If the rental model is chosen, the annual rent can be as low as 5,000 yuan per room.
• Green and environmentally friendly: Factory production is fully controllable, with a corner-material recycling 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 for materials, with a formaldehyde emission of ≤0.05mg/m³, far below the national standard (0.1mg/m³).
• Flexible house types: The standard module size is 6m×3m×3m (length, width, and height). It can achieve free house types through horizontal splicing and vertical stacking (up to 3 floors).

Types and Prices

In Zhejiang, there are various types of cement prefabricated houses, and the prices vary depending on the type. Rural self-built houses, residential and office warehouse cement mobile houses, staffed sentry box supply cement mobile houses, and customized staffed container cement mobile houses are all priced at 300 yuan per square meter. Galvanized steel plate sandwich panel cement prefabricated houses, mobile cement houses, prefabricated cement houses (with 200 styles to choose from), gray-green prefabricated cement houses, and prefabricated cement houses (with fast assembly and splicing construction speeds) are all priced at 1,000 yuan per square meter.
