Zusammenfassung: | The invention relates to concrete doped with steel fibers, and belongs to the technical field of concrete. According to the invention, the maleic anhydride grafted polymer builds a'bridge 'in the steel fiber and the concrete raw material, and the adhesive force between the steel fiber and a matrix is remarkably improved, so that the tensile strength and breaking strength of the concrete are improved; in the preparation of the maleic anhydride grafted polymer, polyacrylate with a fluorine structure reacts with ammonia water to generate amide groups, and hydrogen-bond interaction can be formed among the amide groups of all molecules, so that the tensile strength and the breaking strength of the concrete are remarkably improved; the anhydride group reacts with carboxyl in the carboxylic butadiene-styrene latex emulsion, and the introduction of maleic anhydride can form a cross-linked structure among molecules, so that the tensile strength and breaking strength of the concrete are improved.
