Preparation method of high-strength concrete
The invention discloses a preparation method of high-strength concrete comprising 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, 600 parts of gravels with the particle size of 10-15 mm, 150 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 preparation method of the high-strength concrete is simple and convenient and can make full use of characteristics of all the raw materials, so that the prepared concrete has the strength significantly improved and improved by 50% or more compared with concrete of the prior art; and square piles prepared by the high-strength concrete have higher single-pile bearing capacity.
