Novel high-strength self-compacting concrete
The invention discloses novel high-strength self-compacting concrete including the following raw materials in parts by weight: 3 parts of basalt fibers, 4 parts of glass fibers, 100 parts of cement, 160 parts of fly ash, 800 parts of gravels with the particle size of 10-15 mm, 250 parts of gravels with the particle size of 15-20 mm, 500 parts of sand, 150 parts of water, 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, 0.4 part of a rosin thermopolymer, 0.02 part of a tackifier, 0.4 part of sodium dodecyl sulfate, and 0.4 part of calcium stearate. The novel high-strength self-compacting concrete makes full use of characteristics of all the raw materials, the strength of the prepared concrete is greatly improved and is improved by 50% or more compared with concrete of the prior art, the concrete can be specially used for precast reinforced concrete hollow square piles, and the single-pile bearing capacity of the prepared square piles is higher.
