Three kinds of nano-concrete, i.e., 2.0% nano-SiO 2 doped, 2.0% nano-CaCO 3 doped and 1.0% nano-SiO 2 -1.0% nano-CaCO 3 co-doped concretes (NS, NC, NSC) were prepared for a study on static property and dynamic property under different strain rates (50–130 s −1 ) using HYY series hydraulic servo test...
