Introduction With the advancement of modern engineering structure to the high, large-span and heavy-load direction, more and more severe environmental conditions need to increasingly develop high performance concrete (HPC) to adapt to the engineering construction of concrete, since it can exhibit significantly higher mechanical strengths, better construction workability, volume stability and durability, as well as superior performances under severe conditions in comparison with normal-strength concrete (NSC).

Study on Toughening Cement-based Composites with CaCO3 Whisker and Fiber Mingli Cao1, a, Hang Yao1, b 1School of Civil Engineering, Dalian University of Technology, Dalian, Liaoning, China acaomingli3502@163.com, byao0421@126.com Keywords: CaCO3 Whisker, Polypropylene Fiber, Cement Mortar, Split Tensile Strength, Toughening Mechanism.
Nowadays, the destruction of cement-based materials is mainly due to the low tensile strength, poor impact resistance and high brittleness of matrix [1], which restricts the applications in engineering.
Fiber: polypropylene fiber produced by Shenzhen Wei Te Nai Engineering Material Co., ltd, the main performance parameters are shown in Table 2.
