C120 ultrahigh-strength shrinkage-compensating self-compacting concrete filled steel tube and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses C120 ultrahigh-strength shrinkage-compensating self-compacting concrete filled steel tube and a preparation method thereof. The concrete filled steel tube is prepared from the following raw materials in parts by weight: 61.5 to 68.8 parts of cement, 3 to 15 parts of fly ash microbeads, 1.5 to 7.7 parts of silica fume, 91.1 to 100.7 parts of basalt, 58.2 to 64.4 parts of quartz sand, 0.2 to 0.5 part of expanding agent, 0.2 to 0.6 part of steel fiber, 2.21 to 3.02 parts of water reducing agent and 10 to 15 parts of water. The water-binder ratio is 0.14 to 0.17. The concrete filled steel tube prepared according to the formula has excellent working performance and mechanical performance.
