Novel high-strength concrete for prefabricated reinforced concrete hollow square piles
The invention discloses novel high-strength concrete for prefabricated reinforced concrete hollow square piles. The high-strength concrete is composed of the following raw materials in parts by weight: 3 parts of basalt fibers, 2 parts of steel fibers, 4 parts of glass fibers, 100 parts of cement, 90 parts of fly ash, 900 parts of gravels with the particle size of 10-15 mm, 200 parts of gravels with the particle size of 15-20 mm, 800 parts of sand, 130 parts of water, 1.5 parts of an amino-sulfonate high-efficiency water reducing agent, 10 parts of bentonite, 0.5 part of a super plasticizer, 1 part of an air entraining agent, 0.1 part of a defoaming agent, 0.2 part of a rosin soap, 0.05 part of a tackifier, and 0.3 part of calcium stearate. The novel high-strength concrete for the prefabricated reinforced concrete hollow square piles can significantly improve single-pile bearing capacity of the square piles, has the strength improved by 50% or more compared with concrete of the prior art, and can be specially used for the prefabricated reinforced concrete hollow square piles.
