| Abstract: | Taking the marine engineering of "Underwater World of Tiger Beach Paradise" as an example,the paper introduces a new kind of anti-freezing concrete. By means of this project, an underwater concrete block of 56.06 m long was poured in one time without any contract fissure. It is due to the use of UEA expander,an additive to the concrete,which compensates the contract when the concrete solidifies. Having inspected for three years since it finished,if has shown that the new concrete fulfiled the designed requirements in all aspects. The application of UEA expander in marine concrete has provided a successful experience and found a new way in marine concrete blending. |
