| description | The invention relates to superhigh toughness hollow modified polypropylene fiber sprayed concrete and belongs to hollow modified polypropylene fiber technologies and the technical field of sprayed concrete. The sprayed concrete is composed of materials of, according to the mix proportion, 2%-26.7% of water, 16.7%-52.5% of cement, 12.2%-36.3% of sand, 0.1%-5.5% of hollow modified polypropylene fibers, 13.1%-39% of coal ash, 1.3%-2.8% of superplasticizer, 0.03%-1% of thickening agents and 0.01%-1% of accelerating agents. Fiber is added by means of a first admixing method, and the spraying process uses a wet spraying method. The technical scheme includes that the hollow modified polypropylene fibers are added to the concrete according to a mix proportion, the polypropylene fibers are used as matrixes, a certain mass fraction of cellulose acetate butyrate is added for mixing modified molding, and then the polypropylene fibers and the cellulose acetate butyrate are subjected to processing of drawing and heat setti |
