AI Technical Summary
Technical Problem
It is difficult for existing high-strength concrete to take into account high flowability and high strength in steel pipe concrete structures, and conventional water reducing agents are difficult to meet construction requirements.
Method used
The potassium titanate whiskers are modified using a modified solution made of fatty acid methyl ester, isomer tridecanol polyoxyethylene ether, isotridecanol phosphate, hexafluorobutanol and ethanol. The modified filler prepared is added to the concrete to improve its fluidity and strength.
Benefits of technology
It significantly improves the flowability and strength of concrete, maintains good flowability and self-condensing effect, and meets the construction requirements of steel pipe concrete structures.

Abstract
The present invention relates to the technical field of concrete materials, and specifically discloses a high-strength concrete for preparing a steel tube concrete structure and a preparation method thereof. The high-strength concrete for preparing a steel tube concrete structure includes the following components by mass: 100 parts of water; 208-212 parts of cement; 44-46 parts of fly ash; 86-88 parts of slag powder; 1068-1088 parts of aggregate; 7.4-7.6 parts of admixture; 9-11 parts of modified filler; the modified filler is obtained by modifying potassium titanate whiskers with a modifying liquid; the modifying liquid is a compound of fatty acid methyl ester, isomeric tridecanol polyoxyethylene ether, isotridecanol phosphate, hexafluorobutanol, and ethanol. The present invention has the advantages of making concrete have both high fluidity and high strength.
