High-strength self-compacting concrete
The invention discloses high-strength self-compacting concrete. The high-strength self-compacting concrete comprises raw materials in parts by weight as follows: 3 parts of basalt fibers, 2 parts of steel fiber, 4 parts of glass fiber, 100 parts of cement, 160 parts of fly ash, 800 parts of gravel with the particle sizes being 10-15 mm, 250 parts of gravel with the particle sizes being 15-20 mm, 500 parts of sand, 150 parts of water, 10 parts of bentonite, 0.5 parts of a super plasticizer, 1 part of an air entraining agent, 0.1 parts of an antifoaming agent, 0.4 parts of rosin thermopolymers, 0.02 parts of a tackifier, 0.4 parts of lauryl sodium sulfate and 0.4 parts of calcium stearate. According to the high-strength self-compacting concrete, characteristics of the raw materials are sufficiently utilized, the strength of the prepared concrete is greatly improved and is improved by more than 50% while compared with that of concrete in the prior art, the high-strength self-compacting concrete can be specially used for prefabricated reinforced concrete hollow square piles, and the bearing capacity of a single pile of the square piles prepared from the concrete is higher.
