High-strength self-compacting concrete suitable for steel-concrete combined section and preparation method of high-strength self-compacting concrete
The invention discloses high-strength self-compacting concrete suitable for a steel-concrete combined section and a preparation method of the high-strength self-compacting concrete. The high-strength self-compacting concrete comprises the following components in parts by weight: 200-250 parts of water, 850-855 parts of cement, 230-260 parts of silica fume, 120-145 parts of fly ash, 1000-1100 parts of sand, 6-10 parts of a water reducing agent, 55-65 parts of an expanding agent and 100-130 parts of steel fibers. The high-strength self-compacting concrete is reasonable and scientific in formula, the high-strength self-compacting concrete is prepared through specific components and dosage, the high-strength self-compacting concrete has high strength and high bending resistance, good fluidity and self-compacting performance in the construction process can be guaranteed, and meanwhile the design requirements for durability and the like of a combined section are met.
本发明公开了一种适用于钢混结合段的高强度自密实混凝土及其制备方法，包括以下重量份组分：水200～250份、水泥850～855份、硅灰230～260份、粉煤灰120～145份、砂1000‑1100份、减水剂6～10份、膨胀剂55～65份和钢纤维100～130份。本发明配方合理科学，通过特定的组分和用量制备得到的高强度自密实混凝土，具有高强度高抗弯能力，可保证施工过程中良好流动性和自密实性，同时满足结合段耐久性等设计要求。
