Abstract: The research of experiment focuses on the workability, compressive strength, early cracking, resistance of concrete to chloride penetration, resistance of concrete to freezing and thawing, anti-carbonation properties of C60～C100 high strength and performance concrete. All the properties were compared with C30 ordinary concrete. It also summarizes the materials requirements and mix proportion techniques, and reveals the performance characteristics and change law of C60～C100 high strength and performance concrete. A technical basis is provided for the development of relevant standards of high strength and performance concrete. The results indicate that C60~C100 concrete with good workability, high compressive strength and excellent durability in laboratory, and has great value of the popularization and application.
Keywords: high strength and performance concrete; raw materials; mix proportion; workability; compressive strength; durability
