Preparation method of novel high-strength self-compacting concrete
The invention discloses a preparation method of novel high-strength self-compacting concrete. The novel high-strength self-compacting concrete comprises raw materials in parts by weight as follows: 3 parts of basalt fiber, 4 parts of glass fiber, 100 parts of cement, 160 parts of fly ash, 800 parts of rubble with the particle size of 10-15 mm, 250 parts of rubble with the particle size of 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 a defoaming agent, 0.4 parts of a rosin thermopolymer, 0.02 parts of a tackifier, 0.4 parts of lauryl sodium sulfate and 0.4 parts of calcium stearate. The preparation method of the novel high-strength self-compacting concrete is simple and convenient, characteristics of the raw materials can be fully used, the strength of the prepared concrete is greatly improved and is improved by more than 50% than that of concrete in the prior art, and the single-pile bearing force of a square pile prepared with the method is higher.
