Cement in Prefabricated Houses

The application of cement in prefabricated houses is mainly reflected in cement prefabricated houses, which have the characteristics of being fast, efficient, and low-cost, but also have issues such as design, performance, and safety hazards.

Characteristics of Cement Prefabricated Houses Cement prefabricated houses are used in rural areas of Henan. Their construction process is similar to building with building blocks. After the prefabricated cement slab components are transported to the construction site, they can be quickly assembled. It takes only two days to build an entire building, with a cost of just over 300 yuan per square meter. The cost of constructing a large villa is just over 100,000 yuan, which is much lower than that of traditional brick-and-concrete structures.

Shortcomings of Cement Prefabricated Houses

• Insufficient Design Flexibility: The design of cement prefabricated houses may not be flexible enough to meet diverse architectural needs.
• Performance Needs Improvement: The thermal insulation performance and the earthquake resistance in seismic zones require further research and improvement.
• Critical Connection Issues: The connection between each prefabricated component is crucial. Traditional cast-in-place concrete buildings have walls and floors poured as a whole, providing good integrity. In contrast, if the connections in prefabricated cement block houses are not good, they may collapse during an earthquake.
• High Risk of Water Seepage: As the number of floors increases, the weight borne by the lower prefabricated cement blocks increases exponentially, and the more splices there are, the higher the probability of water seepage in the later stages.
• Poor Sound Insulation: There are gaps at the edges of the panels, resulting in poor sound insulation. The thickness is insufficient, and the structure easily transmits sound.
• Prominent Water Leakage Issues: Water leakage is also a common problem, as rainwater can easily penetrate through the gaps and corrode the steel bars inside.

Market Situation There are many brands of prefabricated cement houses on the market, with varying wholesale prices and market quotations in different regions and among different brands. When choosing a cement prefabricated house, it is necessary to comprehensively consider its characteristics, shortcomings, and the market situation, and weigh the pros and cons before making a decision.
