Tongliao Cement Prefabricated Housing Project

The Tongliao Cement Prefabricated Housing Project features significant characteristics, a wide range of application areas, and a mature technical solution.

I. Core Characteristics and Advantages The cement prefabricated houses in Tongliao are primarily constructed with reinforced concrete structures, offering strong structural stability and high durability, effectively withstanding natural disasters such as earthquakes and strong winds. The prefabricated components are produced in factories to standardized specifications and then transported to the site for assembly, shortening the construction period by approximately 30%-50% while reducing on-site construction errors. The houses utilize insulated sandwich walls (filled with molded polystyrene boards or rock wool) and sealed insulated glass windows and doors, combined with roof and floor insulation layers, achieving warmth in winter and coolness in summer and reducing energy consumption by over 20%. Additionally, the recyclability of cement house materials exceeds 80%, meeting green building standards, with overall costs 15%-20% lower than traditional brick-and-mortar structures and a service life of over 50 years.

II. Typical Application Areas Cement prefabricated houses in Tongliao cater to a variety of scenarios:

1. Temporary Buildings: Such as construction site dormitories and emergency shelters, widely adopted for their rapid assembly capabilities.
2. Permanent Residences: Including rural self-built houses and tourist homestays, balancing affordability and comfort.
3. Public and Commercial Facilities: Schools, clinics, and storage buildings, utilizing modular designs to meet functional expansion needs. For example, Tongliao Jiadun Cement Products Co., Ltd. implemented the annual production of 3,000 prefabricated cement well houses project in the Huatugula Town Industrial Park, Horqin Left Middle Banner, with the first phase producing 2,000 units annually and a total investment of 400,000 yuan, of which environmental protection investment accounted for 37.5%, reflecting a low-carbon construction concept.

III. Moisture-Proof and Insulation Technologies To address the climatic characteristics of Inner Mongolia, prefabricated houses optimize performance through the following measures:

• Moisture-Proof Design: The concrete water-cement ratio is controlled to 0.4-0.5, with the addition of water-repellent admixtures; a moisture-proof layer is set at the foundation, wall joints are sealed with sealant, and a moisture-proof membrane is laid on the floor, effectively blocking moisture penetration.
• Enhanced Insulation: Walls adopt a "concrete-insulation layer-concrete" sandwich structure, with extruded polystyrene boards (XPS) laid on the roof and a 50mm-thick polystyrene board insulation layer added to the floor, combined with airtight windows and doors, ensuring indoor temperature fluctuations of less than 5℃ and adapting to extreme temperature ranges from -30℃ to 35℃.

In summary, the Tongliao Cement Prefabricated Housing Project has become an efficient and environmentally friendly building solution through technological innovation and scenario adaptation.
