Abstract

Abstract

In order to study the dynamic compression mechanical properties of basalt fiber reinforced cementitious composites (BFRCC), different strain rates were applied to three different fiber content BFRCC specimens by using ϕ 50 mm Split Hopkinson Pressure Bar (SHPB) device. Under the dynamic impact compression test, the energy absorption capacity and toughness index of each group of specimens were calculated by the principle of energy conservation. The results showed that the dynamic compressive strength, fracture state and toughness coefficient of cement-based composites with different fiber contents had obvious strain rate effects; with the increase of fiber content,under similar strain rate conditions, the absorbed energy of the specimen showed an upward trend; the toughness coefficient increased with the increase of fiber content.
