The research and development of new cement-reinforced composite materials have promoted the practical application of high-performance concrete.Among them,materials primarily based on fibers and nano-materials have achieved significant progress in modifying cement-based materials.At present,traditional fiber-reinforced concrete has been widely used in practical engineering,and research on new types of fibers with high performance and eco-environmental properties,such as basalt fibers and plant fibers,has received considerable attention.Nano-materials,as a core component in modifying cement-based materials,have a significant effect in enhancing the strength and durability of materials.This paper summarizes the latest research progress in fiber and nano-material reinforced cement-based composite materials and reviews the effects of fibers and nano-materials on the mechanical properties of cement-based materials.
