Embodiment 1
[0030] A high-quality concrete based on nano-bamboo fiber, composed of the following raw materials in parts by weight: 350 parts of Portland cement, 630 parts of river sand, 950 parts of crushed stone, 120 parts of fly ash, 40 parts of S95 mineral powder, 12 parts of modified Nano-bamboo fiber, 30 parts of functional enhancer, 70 parts of nano-silica, 25 parts of nano-carbon fiber, 5 parts of naphthalene-based water reducer, 6 parts of triethanolamine and 180 parts of water.
[0031] The preparation method of modified nanometer bamboo fiber comprises the following steps:
[0032] 1. After drying the nano-bamboo fiber at a temperature of 80°C, immerse it in a hydrogen peroxide solution whose mass is 6 times its mass and whose concentration is 25%, and carry out ultrasonic impregnation treatment on the nano-bamboo fiber at a temperature of 35°C 30min; After the impregnation is completed, it is successively subjected to suction filtration, water washing and drying; the nano-fiber...
Embodiment 2
[0045] The main difference between this example and Example 1 is that the specific ratio of each raw material is different, specifically: 350-380 parts of Portland cement, 630-680 parts of river sand, 950-1020 parts of crushed stone, 120-140 parts of powder Coal ash, 40-55 parts of S95 mineral powder, 12-20 parts of modified nano-bamboo fiber, 30-50 parts of functional enhancer, 70-90 parts of nano-titanium dioxide, 25-35 parts of steel fiber, 5-10 parts of polycarboxylic acid It is a water reducing agent, 6-9 parts of triisopropanolamine and 180-200 parts of water.
Embodiment 3
[0047] The main difference between this example and Example 1 is that the specific ratio of each raw material is different, specifically: 350-380 parts of Portland cement, 630-680 parts of river sand, 950-1020 parts of crushed stone, 120-140 parts of powder Coal ash, 40-55 parts of S95 mineral powder, 12-20 parts of modified nano-bamboo fiber, 30-50 parts of functional enhancer, 70-90 parts of nano-silica, 25-35 parts of polypropylene fiber, 5-10 parts Naphthalene-based water reducer, 6-9 parts of calcium formate and 180-200 parts of water.
