Basalt fiber has the advantages of non-pollution and omnipotence, and expected to be widely used in the 21st Century. Therefore, more and more attention is paid on experimental research of the basalt fiber in the world. Firstly, according to the type selection principles and requirements of the fibers used in the hydraulic concrete, the contrast testing of the plastic shrinkage between fiber cement mortar and pure mortar is made. The experimental results showed that basalt fiber, polypropylene fiber and polyacrylonitrile fiber can be preliminarily chosen as reinforced fibers in high performance hydraulic concrete. Secondly, the impacts of the suggested three sorts of fibers on the interfacial shear stress of the fiber concrete are analyzed by numerical simulation,which showed that maximum interfacial shear stress of the basalt fiber concrete is minimum. So, the bond strength between basalt fiber and concrete is the best. Finally, taking both characteristics of basalt fiber and the increase of concrete costs into account, it can be concluded that top priority should be given to the basalt fiber rather than to other fibers for high performance hydraulic concrete.
