(1) Develop and develop fibers with better performance, strengthen the adhesion between the fiber and the matrix, improve the elastic modulus and anti-aging performance of the fiber, improve the dispersion of the fiber in the matrix, and prevent the deterioration of the performance of the fiber in the cement matrix environment, and reduce the cost.
(2) Research on the relationship between the mesostructure of reinforced fiber reinforced concrete and macroscopic mechanical properties. So far, the discussion of the strengthening and toughening mechanism of organic synthetic fiber concrete is basically a qualitative assumption and theoretical analysis, and the macroscopic performance is the external performance of the microstructure. Strengthening the research in this area and accurately grasping the quantitative relationship between the two can greatly develop the theory of the strengthening and toughening mechanism of polymer fibers.
(3) Carry out test pieces and components to gain an in-depth understanding of the physical and mechanical properties of organic synthetic fiber concrete and the performance of components under various loads, so as to provide a basis for the design of organic synthetic fiber concrete structures.
(4) Selectively carry out construction site tests, master its construction performance indicators, such as mix ratio, mixing method and time control, slump loss, etc., and propose the construction process of organic synthetic fiber reinforced concrete.
