Abstract

The invention discloses carbon fiber concrete and a preparation method thereof, and belongs to the field of concrete. The concrete comprises, by weight, 200 to 300 parts of cement, 800 to 900 parts ofsand, 1010 to 1080 parts of coarse aggregate, 12 to 14 parts of carbon fiber, 20 to 50 parts of aluminum silicate fiber and 10 to 15 parts of aluminate coupling agent. According to the present invention, development of concrete cracks can be effectively inhibited, the tensile strength and toughness of the concrete are increased; the production cost is low; and the thermal conductivity of the concrete of the present invention is significantly suppressed.

Description

technical field [0001] The invention relates to a carbon fiber concrete and a preparation method thereof, belonging to the technical field of concrete. Background technique [0002] Concrete is a basic building material. Concrete is cheap and can be combined with other materials to make various load-bearing fixtures. However, the Achilles heel of concrete is its low tensile strength and easy cracking, which reduces the bearing capacity of concrete structures and shortens their service life. Hidden dangers of various disasters and accidents. In order to avoid these hidden dangers, an additional anti-cracking agent is usually purchased, but the cost is expensive, and the amount of use is not easy to control, which affects the construction progress. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a carbon fiber concrete and its preparation method. [0004] To achieve the above object, the present invention provide...
