Abstract

The invention provides an inorganic-organic composite fiber for a cement-based composite material. The inorganic-organic composite fiber solves the problem of the existing technical scheme. The preparation method comprises adding polypropylene or polyvinyl alcohol fibers into a cement-based composite material and simultaneously, adding basalt fibers into the cement-based composite material. Through an inorganic-organic fiber compounding method, crack resistance, toughness, tensile strength and abrasion-erosion resistance of the cement-based composite material are improved.

Description

technical field [0001] The invention belongs to fibers for cement-based composite materials, and relates to a crack-resistant inorganic-organic composite fiber. Background technique [0002] Existing cement-based composite materials are generally mixed with a single polypropylene fiber or polyvinyl alcohol fiber in order to improve the crack resistance. For example, to improve the toughness, tensile strength and abrasion resistance of cement-based composite materials, generally Steel fiber, such a cement-based composite material mixed with polypropylene fiber or polyvinyl alcohol fiber can enhance the anti-crack and anti-seepage performance, but the toughness, tensile strength and abrasion resistance of the material cannot be effectively improved. Although the cement-based composite material of steel fiber can improve the toughness, tensile strength and abrasion resistance of the material, the improvement of micro cracks is not obvious. [0003] In recent years, the use of ...
