US 2021/0070657 A1 · TEXTILE-REINFORCED CEMENT COMPOSITE FOR SUPPRESSING OCCURRENCE OF SLIPPING AND CRACK AND METHOD OF MANUFACTURING THE SAME

Abstract

Provided are a textile reinforced cement composite for suppressing occurrence of slipping and a crack and a manufacturing method thereof. The textile reinforced cement composite for suppressing occurrence of slipping and a crack can suppress slipping between a textile grid reinforcement and a cement composite by using an angulated filling material mixed therewith when a textile reinforced cement composite having a textile grid reinforcement embedded in a cement composite is manufactured, suppress occurrence of a crack of the cement composite, suppress occurrence of a crack of the cement composite due to a fiber bridging reaction by using organic fiber mixed therewith, induce distribution of fine cracks, suppress degradation of fluidity of the cement composite caused by mixing of the angulated filling material by using a spherical binder and a chemical admixture added thereto, and suppress slipping between the textile grid reinforcement and the cement composite by using a fine powder binder having a predetermined particle size and mixed therewith.

Dependent claims

A textile reinforced cement composite for suppressing occurrence of slipping and a crack, the textile reinforced cement composite comprising:

a cement composite formed by mixing a fine powder binder, an angulated filling material, and an organic fiber with cement so that slipping on an interface with a textile grid reinforcement and occurrence of a crack are suppressed;
and
the textile grid reinforcement embedded and disposed in the cement composite to reinforce the cement composite,
wherein the cement composite is formed by mixing 100 parts by weight of the cement, 40 to 60 parts by weight of a spherical binder, 10 to 30 parts by weight of the fine powder binder, 180 to 225 parts by weight of general sand, 75 to 120 parts by weight of the angulated filling material, 55 to 75 parts by weight of mixing water, 0.5 to 2.5 parts by weight of the organic fiber, and 0.1 to 0.3 parts by weight of a chemical admixture,
the angulated filling material suppresses slipping between the textile grid reinforcement and the cement composite and occurrence of a crack of the cement composite,
the fine powder binder has a predetermined particle size and suppresses slipping between the textile grid reinforcement and the cement composite, and
the organic fiber suppresses occurrence of a crack of the cement composite due to a fiber bridging reaction and induces distribution of fine cracks.
