Jiangxi Cement Prefabricated Houses

There are cement prefabricated house-related industries in Jiangxi Province, and some products have good performance, but some early prefabricated cement slab houses have aging issues.

I. Current Situation of the Cement Prefabricated House Industry in Jiangxi Province Jiangxi Province has industries related to cement prefabricated houses. For example, Jiangxi Jintai Prefabricated Building Co., Ltd. produces light-steel composite cement prefabricated houses. These houses are cast in one piece in the factory using C30 national standard concrete and national standard threaded steel. Their wall strength is 130% higher than that of traditional brick-and-mortar structures, and they have significant features such as earthquake resistance, fire resistance, and durability. In terms of earthquake resistance, they can withstand magnitude-8 earthquakes and force-12 strong winds, providing reliable safety guarantees for occupants. Regarding fire resistance, they can effectively prevent the spread of fire, safeguarding life and property. In terms of durability, they have waterproof, anti-corrosion, and anti-aging properties, extending the service life of the houses.

II. Problems with Early Prefabricated Cement Slab Houses A large number of houses in the old urban area of Nanchang once used prefabricated cement slabs for heat insulation and waterproofing. However, after decades of exposure to the elements, these houses have generally experienced problems such as roof leakage and heat insulation failure. This is mainly because early prefabricated cement slabs may have had certain limitations in manufacturing processes and material selection. Over time, affected by natural environmental factors such as rain erosion and temperature changes, their performance gradually declined. Roof leakage not only affects the normal use of the houses but may also pose a threat to their structural safety. Heat insulation failure can result in excessively high indoor temperatures in summer and excessively low temperatures in winter, reducing living comfort.

III. Implications for Future Development From the development of cement prefabricated houses in Jiangxi Province, on the one hand, modern advanced cement prefabricated house technologies have significant advantages and development potential and should be further promoted and applied to meet people's demand for high-quality housing. On the other hand, the problems with early prefabricated cement slab houses need to be taken seriously. In subsequent house construction, renovation, and maintenance, full consideration should be given to the durability of materials and the rationality of processes to improve the overall quality and service life of houses.
