Cement Prefabricated Wall House

Cement prefabricated wall houses mainly include four types: prefabricated fences, cement prefabricated panel wall houses (early form), prefabricated reinforced concrete houses (new type of cement houses), and prefabricated cement integrated houses.

Prefabricated fences: These are prefabricated in factories using materials such as cement and magnesium chloride and assembled on-site using embedded parts and other components. They have a compressive strength of 21.3 - 31.0 Mpa, support various decorative styles, and are reusable, have a short construction period, and can be constructed in winter. They have been extended to high-altitude and cold regions.

Cement prefabricated panel wall houses (early form): These use Portland cement and steel reinforcement frames as the main materials and are prefabricated into panel-shaped walls using molds. They are divided into solid and hollow types. Hollow prefabricated panels can reduce weight and cost. Their standard specifications have a maximum span of 4.2 meters and thicknesses mainly of 120 mm and 150 mm. The advantages are simple construction techniques, low price, and light load; the disadvantages are that panel joints are prone to cracking and leaking, insulation performance is poor, and load-bearing capacity is weak. They are currently prohibited or rarely used.

Prefabricated reinforced concrete houses (new type of cement houses): These adopt a factory prefabrication + on-site assembly model. Core components are cast in one piece using high-precision molds and integrate multiple structures such as steel reinforcement frames and insulation layers. They have a compressive strength of 25 - 30 MPa, a wind resistance rating of 10, and a seismic fortification intensity of 7 degrees. The advantages include:

• High efficiency: A single 30㎡ module takes only 7 days to prefabricate in the factory and 4 hours to install on-site. A 100㎡ house can be fully constructed in just 2 days;
• Low cost: The cost of the main module of a 120㎡ rural self-built house is 30% lower than that of a traditional brick-concrete structure;
• Green and environmentally friendly: Construction waste is only 10% of that of traditional house construction, and formaldehyde emissions are far below national standards;
• Flexible space: Modules can be spliced and stacked to achieve free layout of house types.

Prefabricated cement integrated houses: Wall and floor panels are prefabricated in the factory and hoisted on-site. The main structure of a 200㎡ villa can be completed in 4 hours, saving 90% of the time compared to traditional construction and significantly reducing labor costs. They use a C35 concrete and thickened steel reinforcement frame and can withstand typhoons of level 12, but custom styling requires an additional fee.
