- Succeeded in experiment for transfer of high strength fire-proof concrete (100Mpa) certified by Fire Insurers Laboratories of Korea up to height of 600m under pressure - Developed and applied for patent registration for high pressure pipe and management system for the first time in Korea - To be applied at the time of construction of Global Business Center(GBC) at Ttukseom
HYUNDAI AMCO succeeded in developing technology for pressurized transfer of concrete for ultra-high rise buildings.
HYUNDAI AMCO, a subsidiary construction company of Hyundai Motor Group of Companies (Representative Director: Kim, Chang Hee; www.hyundai-amco.co.kr), announced that the company succeeded in development of high-strength fire-proof concrete, high pressure pipe and management system to be applied to high-rise building, and the experiment to transfer concrete under pressure (shooting up the concrete by means of pump car) to the height of up to 600m.
This experiment was carried out recently at the Hyundai Cement Distribution Base in Yongin City, Gyeonggi-do to evaluate the transfer capability under pressure for the purpose of application at the time of construction of Global Business Center (GBC), ultra high rise building in Ttukseom in advance.
Although there have been total of 5 cases of experiment on transfer capability under pressure using high strength concrete by domestic construction companies, HYUNDAI AMCO was the 2nd company in Korea, following the L Construction (80Mpa) that recent carried out experiment to examine the transfer capability under pressure by using concrete certified for its fire-proof properties by the Fire Insurers Laboratories of Korea.
Concrete (100Mpa) that HYUNDAI AMCO upgraded and developed has the highest strength among those that are being commercialized by having actually been certified. High strength concrete for ultra-high rise buildings is stronger than the ordinary concrete. Therefore, it is most important to apply concrete that has been certified for its fire-proofing properties that evidence how well it withstands high temperature because high strength concrete that has not been certified can explore due to high temperature in the event of fire.
100 Mpa concrete that HYUNDAI AMCO applied to this experiment has extremely high strength in addition to having outstanding fire proof properties. This strength is sufficient for create with dimension of 1mx1m to support approximately 7,300 units of 2,000CC Sonatas with approximate net weight of 1.4 tons each.
In the experiment, HYUNDAI AMCO introduced high pressure pipe and management system for ultrahigh rise buildings that the company developed for the first time in Korea. In particular, the company announced in-house assessment that the high pressure pipe has outstanding performance of being able to send up concrete up to the ultrahigh rise building height of 500m∼550m without replacing of the pipe (until the completion of the building).
Among the high pressure pipe for ultrahigh rise buildings, although that applied to construction of Burj Khalifa in the Middle East in fact has monopoly in the market due to its outstanding performances, HYUNDAI AMCO managed to domesticate and develop pipe with 2 times the pressure resistance at half the cost.
Moreover, the management system that HYUNDAI AMCO developed at the same time has the advantage of being able to check current status of pressure and prevent blocking of the concrete within the pipe through sensor and monitor at each section of the pipe when shooting the concrete upwards, and transfer the concrete through detour pipe through automatic control in the event of such occurrence (blocking of the pipeline by concrete).
Such technological achievement is the results of coexistence cooperation through joint development with Hyundai Hysco, a subsidiary steel pipe manufacturing company of the Hyundai Motor Group of Companies and Sampyo Co., Ltd, a cooperative company. HYUNDAI AMCO has recently applied for patent for this technology and is planning to complete registration of the patent by next year.
Mr. Jeon, Chang Young, the director of technology research institute of HYUNDAI AMCO, stated that the “advanced technological capabilities of our company have been recognized through the modulization process applied to the company building of Hyundai Motors in Yangjae-dong and maritime Floating Dock (F/D) process applied to the port construction at Dangjin for Hyundai Steel Mill “ and that “this experiment for technology for pressurized transfer of concrete for ultrahigh rise buildings is significant in that the company has secured technological competitiveness at the time of construction of Global Business Center (GBC) in Ttukseom in the future.”
On the other hand, HYUNDAI AMCO is assertively pursuing technological development related to construction of ultrahigh rise buildings including impact absorption technology to reduce the damages to structures arising from gale and earthquake in the future.
