Shenzhen lightweight concrete manufacturers in Shenzhen Jin Jianda construction company to introduce the development of foam concrete process. Entering the 21st century, foam concrete blocking the runway at the airport system, high-speed rail and highways acoustic sound field, energy-absorbing area and absorbing refractory material is widely used in the field. Since 1979, more than 30 years, is improvement of foam concrete technology and application of rapid expansion phase. At present, its application field has reached more than 20 more, and extended from the civilian to the military, aerospace, industrial applications, such as high end, opening up wide path for its future development. Currently, foam concrete is the most developed of the three areas are: Europe, North America, Asia, Japan and South Korea and Southeast Asia.
Due to the technical support of the former Soviet Union, China's development of the foamed concrete is not late, second only to Europe. On one hand, in the former Soviet Union industrialized production of foamed concrete technology and construction design, construction and engineering acceptance of, go in the early 1950 of the 20th century in the world. The other hand, but China comes as the former Soviet Union built a critical period for foamed concrete technology in China at that time to provide a social and historical conditions.
In 1950, the experts from the former Soviet Union started promoting the foamed concrete technology to China. In 1952, the Chinese Academy of Sciences, Institute of civil engineering and architecture set up foam concrete laboratory, led by Huang Langu, began a study of foam concrete in China. At that time the steam pipe must be imported from the former Soviet Union suweilite magnesium Board, per ton including freight of about 1400 Yuan, while China is in a period of mass construction, industrial pipe insulation in great demand, especially in power plants, a generator you need 260 tons of insulation, cost is very high. So my initial research and development of foam concrete of the first objective, that is, pipe and tank insulation materials used in solving problems. In 1952, the second machinery Ministry of the fourth design, heavy industry, non-ferrous metal production of foamed concrete such as authority, and successfully applied in industrial pipe insulation. In 1954, in cooperation with the Institute of civil engineering and other units, guided by experts from the former Soviet Union, producing autoclaved foam concrete slabs in Harbin and Harbin electrical measuring instrument factory of roof insulation, this is the first time that foam concrete used in building insulation. 1955-1957, Institute of science and technology of the Ministry of water resources and electric power construction was successfully trial-produced temperatures of up to 250~510du of foam concrete shell and application in the peak peak power plant, Dalian power plant heat pipe insulation. In 1956, the former textile industry capital Institute also carried out experimental study of flyash foamed concrete, replacing cement with fly ash to reduce costs, mainly because when foam concrete with cement, costs are higher. In the second Department of Beijing Municipal Bureau of construction materials, textile engineering company and cooperation of water conservancy Science Research Institute and other units, after a year of experiments had been successful, cost of foamed concrete has 40%, in construction application effect was good.
Can say 1952-1959 8 years, is the development of foam concrete the first orgasm, our foam concrete industry formed a certain scale of production. Subsequent deterioration of Sino-Soviet relations, experts from the former Soviet Union withdrawal, coupled with the subsequent cultural revolution, 20 years of foam concrete technologies and industrial production stagnated.
Development of foam concrete the second orgasm followed after the roof insulation and in-situ foam concrete, and in the 1950 of the 20th century, the first high mainly in the foamed concrete products are fundamentally different in the new era. In 1980, China began its reform and opening up, while European foam concrete in-situ technologies into our open frontier area in Guangdong Province. Guangdong and around area summer hot, on roofing insulation insulation needs strongly, bubble concrete now poured roofing first in Guangdong popular up, at, Guangzhou, and Dongguan, and Foshan, to, large of roofing insulation insulation are application has now poured of bubble concrete, thereafter, bubble concrete roofing insulation insulation now poured technology gradually to North advance, by Fujian, and Hunan, and Jiangxi, province way North, anti-exhibition to Beijing, and Liaoning and Shaanxi, to, again Hou promotion to country, now poured bubble concrete Foamed concrete and has become a major area of application.
