Hunan Yueyang Cement Prefabricated Houses
The development of cement prefabricated houses in Yueyang, Hunan, has gone through stages from emergence, pilot projects, promotion to gradual phase-out. Currently, there are still relevant enterprises engaged in the production and sales of prefabricated components.
Development History: In 1958, due to tight wood supply, prefabricated components such as cement hollow floor slabs began to be used in urban housing construction in Yueyang. Sidewalk bricks for street construction were also replaced by self-made cement prefabricated components. In July 1962, the Hunan Provincial Basic Construction Bureau determined three rural housing plans assembled with prefabricated components and conducted pilot projects in Yueyang County. The Yueyang County Basic Construction Bureau built single dormitories in Mahao Li, Chengguan Town, and a T-shaped three-story office building for the Yueyang County Tax Bureau on Nanzheng Street, both using cement brick arch structures. However, due to the high cost of reinforced concrete, heavy components, and the underdeveloped rural economy, these plans were not promoted in rural areas. After the Third Plenary Session of the 11th Central Committee of the Communist Party of China, urban infrastructure construction and rural housing construction surged, leading to the emergence of cement prefabricated component enterprises. In 1984, prefabricated component supply companies were established in each county to be responsible for the production of rural housing components. In 1986, Quyuan Rural Housing Construction Materials Company supplied 24 commercial houses to farmers, which were two-story brick-concrete structures with an area of 130 - 150 square meters and a cost of 120 - 140 yuan per square meter.
Current Situation: Prefabricated slab housing has problems such as poor seismic performance and failure to meet secondary fire resistance standards. Yueyang City has stopped using prefabricated slabs for housing construction, and economically better counties (cities) and districts are also gradually switching to cast-in-place concrete, such as Linxiang City. However, there are still relevant enterprises in Yueyang City engaged in the production and sales of prefabricated components. Yueyang Hongdu Concrete Prefabricated Components Co., Ltd. (renamed to Hunan Changtong Concrete Prefabricated Components Co., Ltd. on April 18, 2022) has a business scope including the production and sales of prefabricated components.
Characteristics and Impact: Cement prefabricated houses solved the problem of tight wood supply during a specific historical period and promoted the development of urban and rural construction. However, due to the limitations of technology and materials at that time, there were many problems. With the progress of construction technology and the increasing demand for building quality, they have gradually been replaced by safer and more durable construction methods.
