Title: The introduction of anti-washout concrete in the arrival shaft for the discharge tunnel of the 4th nuclear power plant
Author(s): C. C. Lin
Publication: TCI Concrete Technology
Appears on pages(s): 10-16
Keywords: anti-washout concrete, underwater non-separation agent, mobile agent, water-cement ratio
Abstract:The anti-washout concrete has been used for more than 30 years in Japan, and it is considered as avery high reliable material that is commonly used in marine engineering. However, there is no experience of the past on the use of anti-washout concrete in Taiwan. The discharge tunnel of the Fourth Nnuclear Power Plant faces the Pacific Ocean, and is subjected to the impact of typhoons and strong waves. The requirements of structural strength is are very important. So we decided to backfill with anti-washout concrete in the arrival shaft to ensure engineering quality. Using the experience of Japanese, we developed the concrete mixture design.and performed a site test in the sea to evaluate the quality requirements (anti-washout, flowability, strength, etc.). Finally, under careful planning, the mass production of the anti-washout concrete was produced by the batching plant and the underwater placement was successfully completed. We got good quality concrete by verifying the concrete strength evaluation. With the experience of using anti-washout concrete, we hope it can be widely used to enhance the level of domestic marine and underwater engineering technology in the future in Taiwan.
