Embodiment 1
[0017] A carbon fiber concrete, calculated by weight, includes 200kg of cement, 800kg of sand, 1010kg of coarse aggregate, 12kg of carbon fiber, 20kg of aluminum silicate fiber, and 10kg of aluminate coupling agent. The coarse aggregate includes small stones with a particle size of 5-20 mm and medium stones with a particle size of 20-40 mm, and the ratio of small stones to medium stones is 6:4.
[0018] Based on above a kind of carbon fiber concrete, its manufacture method comprises the following steps:
[0019] Step 1: Mix and dry mix 200kg of cement, 800kg of sand, and 1010kg of coarse aggregate;
[0020] Step 2. Dissolve 10kg of aluminate coupling agent in water to make a solvent. Add 12kg of carbon fiber and 20kg of aluminum silicate fiber into the solvent and stir evenly. When carbon fiber and aluminum silicate fiber are added to the solvent and stir, the temperature of the solvent is 40°.
[0021] Step 3, adding the solution obtained in step 2 to the mixture obtained i...
