( Pengjian, Shandong Construction Engineering Group Co., Ltd., Penglai 265600, China)Abstract: Penglai Ancient Boat Museum underground engineering structural design life span of 100 years, high-performance durability concrete C45 DF70 Plo was used in this project. Concrete construction of the project had a difficult mix design, construction and high control requirements. Therefore, from the raw materials, key link in the concrete configuration with design than with the three aspects of testing and strict quality to raw materials, metrology, stirring, vibration and clean surface and conservation areas such as construction control measures were introduced. The experimental results show that mixing fly ash, polypropylene fiber, inhibitor, high-activity water reducing agent and concrete air-entraining agent have a very good blending and make the concrete to meet requirements ofhigh performance and high-durability mechanical performance.
