摘要：

The nanomaterials-modified strain hardening cementitious composites were prepared in this study. The split Hopkinson pressure bar technique was used to conduct the dynamic compressive test. The dynamic compressive properties were evaluated and compared with the quasi-static properties. The experimental results indicated that the addition of nanomaterials had positive effect on improvement of the strength and toughness of strain hardening cementitious composite. The strain hardening cementitious composite with and without adding nanomaterials showed an obvious strain rate dependence, and the nanomaterials-modified strain hardening cementitious composite was more sensitive to the strain rate.
