Embodiment
[0019] A carbon fiber coral concrete is composed of coral concrete and carbon fiber. The volume percentage of the two components is: 99.88% coral concrete and 0.12% carbon fiber.
[0020] The coral concrete is coral concrete of C30 grade, and its components per cubic meter are: 450 kilograms of cement, 830 kilograms of medium sand, 716 kilograms of coral and 180 kilograms of seawater; wherein: the cement is ordinary Portland cement with a label of 42.5; The medium sand is natural medium-coarse river sand with good particle gradation; the coral is the coral sand distributed on Weizhou Island in the North Sea, and its shape is strip and block. The strip coral sand is 2-4 cm long and 1.5±0.02 in diameter The length and width of massive coral sand is 2~3 cm, and the diameter is 1.5±0.02 cm. Strip coral sand accounts for 25.7% of the total weight of coral sand; seawater is prepared with sea salt according to the composition of South China Sea seawater.
[0021] The carbon fiber has...
