Effect of Using Plant Fiber on The Properties of Concrete

With light weight, wide sources, low cost and renewable, plant fiber concrete has become the preferred green building materials. This paper reviews the research status of bamboo fiber, flax, hemp, jute, ramie and other high-strength plant fibers, and discusses their basic properties and defects, such as strength, interface bonding, thermal insulation, as well as fiber corrosion, adhesion, water absorption and workability. In view of these, the strategies of pretreatment, use of mineral admixtures, optimization of bonding materials and improvement of mixing process are put forward. The results show that reasonable improvement measures can significantly improve the performance of plant fiber concrete. This paper provides theoretical and technical support for the application of plant fiber concrete, and looks forward to its wide application prospect in the field of civil engineering.
