Taigu Cement Prefabricated Housing

The development of Taigu cement prefabricated housing shows a trend of upgrading traditional techniques and integrating modern technologies, presenting both innovative breakthroughs and challenges in upgrading traditional products in terms of performance, manufacturing, and rural applications.

Product Performance Transformation: From Single Structure to Multi-functional Integration

Traditional cement products primarily focus on mechanical properties, while enterprises in Taigu County have achieved three major upgrades through technological innovation:

1. Refinement of Mechanical Properties: Optimized designs for different scenarios. For example, permeable bricks for sponge cities achieve a connected porosity of 20%-30% by adjusting aggregate gradation and bonding methods, while meeting road paving standards for compressive strength, balancing permeability and load-bearing capacity.
2. Introduction of Non-mechanical Functional Attributes: Development of composite thermal insulation exterior wall panels that integrate thermal insulation material layers, reducing construction steps and lowering the risk of thermal bridges; ecological slope protection bricks with reserved holes or special textures achieve synergy between engineering protection and ecological restoration, expanding the application boundaries of cement products.
3. Predictability of Long-term Service Performance: By incorporating mineral admixtures such as fly ash and slag, along with high-efficiency water reducers, the microstructure is improved, enhancing durability against freeze-thaw cycles and sulfate attack. This approach is more scientific than simply increasing cement content in traditional methods, extending product service life.

Manufacturing Logic Transformation: From Experience-driven to Process-controlled

Enterprises in Taigu County are gradually abandoning traditional experience-based production and transitioning to modern control. For example, Hongxing Prefabrication Factory, a local small and micro enterprise founded in 1985, has incorporated process-controllable methods, improving product consistency through standardized processes and laying the foundation for large-scale production.

Industry Case Reference: Industrial Thinking Enhances Efficiency

The prefabricated cement house project in Qixian, Henan Province, demonstrates the potential of modern technology integration:

• Factory Prefabrication and On-site Hoisting: A single module production cycle of 7 days with an error margin controlled within 2 millimeters; on-site completion of a 200㎡ three-story villa's main structure installation in 4 hours, achieving the efficiency of 'building one house per day,' reducing labor costs by 60%, and minimizing construction waste by 98%.
• Technical Core Support: Adoption of a full-frame shear wall structure (C35 concrete + Φ14 threaded steel bars, with a reinforcement ratio of 1.2%), mortise-and-tenon + bolt dual connections (with a tensile strength of 25 tons), and an intelligent integrated system (pre-embedded EPS insulation layers in walls, reserved photovoltaic panel interfaces on roofs), significantly enhancing earthquake resistance, thermal insulation, and energy self-sufficiency.

Rural Application Controversy: Traditional Prefabricated Panel Houses Need Upgrading

Although traditional prefabricated panel houses are popular in rural areas due to their low cost and fast construction, they have prominent issues such as safety hazards (e.g., collapse during earthquakes), poor sound insulation (structural sound transmission), and water leakage (corrosion of steel bars in panel joints). Experts recommend phasing out these traditional houses and promoting a transition to safer, more functional modern cement prefabricated housing.
