Carbon fiber coral concrete and preparation method thereof

Abstract

The invention discloses carbon fiber coral concrete and a preparation method thereof. The carbon fiber coral concrete consists of coral concrete and carbon fibers, wherein the coral concrete is at the grade of C30; the coral concrete of each cubic meter comprises the following components: 450 kg of cement, 830 kg of medium sand, 716 kg of corals and 180 kg of seawater; the length of the carbon fibers is 20 mm; the tensile strength is greater than 3,000 MPa. The carbon fiber coral concrete is prepared by pouring the sand and the corals into a stirrer, stirring, adding the carbon fibers, stirring uniformly in a dry state, adding 1/2 seawater and stirring, finally adding the cement and the remaining seawater and stirring uniformly. The carbon fiber coral concrete disclosed by the invention has high splitting tensile strength and breaking strength, meanwhile, has high toughness and crack performance, has the advantages of light weight, high convenience, low construction cost, high heat preservation and insulation performance and the like, and can be widely applied to the field of marine civil engineering.

Description

technical field [0001] The invention belongs to the technical field of building engineering materials, in particular to a carbon fiber coral concrete and a preparation method thereof. Background technique [0002] With the acceleration of my country's development of the South China Sea and the modernization of national defense, it is urgent to carry out basic civil engineering construction around the ocean. Under the premise of not destroying the local ecological environment, coral concrete is prepared based on coral reefs instead of coarse aggregates and seawater instead of fresh water. It has great practical significance in civil engineering and military engineering. Compared with ordinary concrete, coral concrete is lighter in weight, and has the advantages of strong anti-seepage and crack resistance, good heat insulation effect, strong anti-freezing and anti-fatigue ability, and good durability. Small modulus, easy to crack, high chloride salt content and other shortcomi...
