New Type Prefabricated Cement House

The new type prefabricated cement house takes prefabricated reinforced concrete modules as its core and is an assembled house produced in factories and assembled in a modular way.

Core Process and Structure: At specialized production bases, core components such as walls, floors, beams, and columns are cast in one go using high-precision molds. Each module integrates multiple structures including a steel reinforcement framework, insulation layers, waterproof layers, and pre-embedded pipelines, allowing for flexible combination like 'building blocks'.

Core Technical Highlights:

• High Strength: 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-mortar structures.
• Good Thermal Insulation: The walls have reserved slots for EPS insulation layers. When embedded on-site, the thermal insulation performance can be improved by 40%, providing significant warmth in winter and coolness in summer.
• Strong Wind and Earthquake Resistance: The modules are connected through pre-stressed bolts + welded steel plates to form an overall framework. It can withstand wind speeds of up to Class 10 and has a seismic fortification intensity of 7 degrees (equivalent to the destructive force of the Wenchuan earthquake). There are also claims that it can actually withstand a typhoon of Class 12 in actual measurements, and in simulation tests, the house only shifts by 3 centimeters when swaying.

Advantages Compared to Traditional House-Building Methods:

• High Efficiency: Traditional self-built houses take 3 - 6 months from bricklaying to completion, while a single 30㎡ module of the cement house only takes 7 days for factory prefabrication. After being transported to the site, with the cooperation of a crane and 3 workers, a single module can be installed in 4 hours, and a 100㎡ house can be fully erected in just 2 days.
• Low Cost: Taking a 120㎡ rural self-built house as an example, the cost of a traditional brick-and-mortar 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, reducing the overall cost by 30%.
• Green and Environmentally Friendly: 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-building. Environmentally friendly concrete and water-based paints are used, with a formaldehyde emission of ≤0.05mg/m³, far below the national standard (0.1mg/m³).
• Flexible House Type: The standard module size is 6m×3m×3m (length, width, and height). It can achieve free house type design through horizontal splicing and vertical stacking (up to 3 floors).

Limitation: It is difficult to modify the shape. If you want a rounded balcony, you have to pay an additional 20% for customization.
