Gannan Cement Prefabricated House

Gannan cement prefabricated houses are prefabricated buildings formed by assembling factory-prefabricated components on-site. They feature standardized production and strong climate adaptability, but specific prices need to be determined based on specifications and suppliers.

Industrialized Production Mode of Prefabricated Components

The core of Gannan cement prefabricated houses lies in the factory-prefabricated production of building components. For example, the prefabricated lightweight partition panels in the Gannan region are formed into standardized panels through processes such as mold design, pouring of mixed slurry (e.g., cement, lightweight aggregates, etc.), compaction, curing, and demolding. This industrialized production mode achieves standardization and modularization of building components, providing a solution for factory-based manufacturing and rapid on-site assembly for interior partition wall projects, significantly shortening the construction period and reducing the complexity of on-site operations.

Adaptability of Materials to Plateau Climate

The Gannan region has a plateau climate with large diurnal temperature variations and frequent freeze-thaw cycles, imposing high durability requirements on building materials. Prefabricated components demonstrate good adaptability in this environment:

• Frost resistance: The prefabricated lightweight partition panels have a low moisture content, with a strength loss of less than 5% after 25 freeze-thaw cycles, effectively reducing the risk of freeze-thaw damage.
• Deformation resistance: The drying shrinkage value is controlled within 0.6 millimeters per meter, avoiding significant deformation caused by humidity changes and ensuring the long-term stability of the walls.

Market Price Reference and Regional Differences

The prices of cement prefabricated houses vary depending on specifications, materials, and suppliers. According to currently available data, the price of prefabricated cement houses in Jinchang, Gansu is 1000 yuan per square meter, while some products in Zhumadian, Henan are priced between 300 and 350 yuan per square meter, and the price of prefabricated cement houses in Jining, Shandong is 600 yuan per square meter. However, it should be noted that these cases do not explicitly indicate whether they are products from the Gannan region. Actual prices may vary due to factors such as transportation costs and localized production, and need to be determined through negotiation with suppliers based on specific needs.

Relevance of Construction Techniques

The application of foam concrete cast-in-place walls in the Gannan region shows that the cast-in-place technique can enhance the overall integrity of walls, avoiding the thermal bridge effect caused by poorly compacted mortar joints in traditional block walls. This characteristic has reference value for the joint sealing design of cement prefabricated houses. For example, by optimizing component connection nodes and using elastic sealing materials, the thermal insulation performance and airtightness of prefabricated houses can be further improved to adapt to the severe cold climate of the plateau.
