Cement Prefabricated Rural Houses
Cement prefabricated rural houses were once quite popular in rural areas, characterized by fast construction speed and relatively low costs, but they also have defects such as safety hazards, poor sound insulation, and prominent water leakage issues.
In terms of construction speed, cement prefabricated rural houses have significant advantages. In rural areas of Henan, there have been cases where a villa was completed in four hours and a building was constructed in two days. There are also examples of using prefabricated components for assembly, with the main structure completed in 14 days. This rapid construction is due to the prefabricated components being made in advance in factories, with only assembly and installation required on-site, greatly shortening the construction period and quickly meeting rural housing demands.
In terms of cost, compared to traditional construction methods, cement prefabricated rural houses have lower costs. In rural areas of Henan, cement prefabricated houses made of reinforced concrete cost over 300 yuan per square meter. Wholesale prices vary in different regions, such as 260 yuan/square meter and 400 yuan/square meter in Jining, Shandong, and 210 yuan/square meter and 400 yuan/square meter in Shijiazhuang, Hebei. The relatively low cost makes it easier for rural families to afford economically, becoming one of the important reasons for its popularity.
However, cement prefabricated rural houses have many problems. There are significant safety hazards. These houses may collapse even in minor earthquakes. The quality of prefabricated cement slabs on the market varies greatly, with most being of inferior quality and having a short service life, which can lead to house collapse accidents. The sound insulation is poor. The thickness of prefabricated panels is usually around 10 centimeters, with long circular holes in the middle. The insufficient thickness and sound-conductive structure result in poor sound insulation. Noise from neighboring rooms can be transmitted through the holes and may even be amplified. The water leakage problem is prominent. Prefabricated panels are assembled from independent sections, with tiny gaps between them. During the rainy season, rainwater can easily seep through these gaps into the interior, corroding the steel bars and affecting the structural safety and service life of the house.
Overall, although cement prefabricated rural houses have advantages in terms of fast construction and low cost, problems such as safety hazards, sound insulation, and water leakage cannot be ignored. Comprehensive consideration is required when choosing a construction method.
