Prefabricated Cement Assembled House

A prefabricated cement assembled house is a type of housing that divides the house into multiple components, which are prefabricated in a factory and then transported to the site for assembly. It offers numerous advantages but also comes with some considerations.

Material and Structure

It is constructed using reinforced concrete, with a framework built from Φ10 - Φ14 national standard threaded steel bars and poured with C35 concrete as a whole. Each module weighs over 20 tons, with wall thickness ranging from 150 - 200mm and floor slab thickness of 120mm, forming a sturdy structural system.

Advantages

• Fast Construction Speed: Standardized factory production allows a single module (30㎡) to be completed from steel bar binding to concrete pouring in just 7 days, unaffected by weather conditions. On-site lifting is highly efficient; with a 50-ton crane and 3 workers, a single module can be lifted in 4 hours, and a 100㎡ house can be fully installed in just 1 day, reducing the construction period by 90% compared to traditional methods.
• Low Cost: It offers a price advantage, costing over 300 yuan per square meter. The main structure of a 100㎡ house can be completed for 100,000 - 120,000 yuan, which is 30% cheaper than brick-and-mortar construction.
• High Safety Performance: It can withstand earthquakes of magnitude 8, with wall crack widths controlled within 0.2mm and no damage to the main structure. It has strong wind resistance, with no loosening of module connections under a 12-level typhoon. Its fire rating is high, with a fire resistance limit of over 3 hours for the concrete.
• Environmentally Friendly and Energy-Efficient: It generates less construction waste; a 120㎡ assembled cement house produces only 1.5 tons of construction waste, a 90% reduction compared to traditional brick-and-mortar structures. The pre-embedded insulation layer saves half of the heating costs in winter, and the formaldehyde content is only one-third of the national standard.
• Flexible and Durable: It has a wide range of applications, with a house lifespan of up to 70 years, and can even be rented on a monthly basis for short-term use.
• Reusable: It can be disassembled and reassembled like building blocks.

Price

Prices vary by region, brand, and specification, ranging from 220 - 1100 yuan per square meter. Some are also sold by the set, such as an assembled cement mobile house in Jining, Shandong, priced at 7500 yuan per set.

Considerations

The shape is difficult to modify; for special shapes like rounded balconies, an additional 20% customization fee is required. When purchasing, choose reputable brands like Broad Homes, and demand a 70-year warranty and seismic report. A comprehensive package can be completed for under 150,000 yuan.
