Super-early-strength type ultra-high performance concrete and preparation method thereof
The invention discloses super-early-strength type ultra-high performance concrete and a preparation method thereof, and belongs to the technical field of building materials. The super-early-strength type ultra-high performance concrete is prepared from the following components in parts by weight: 50 to 100 parts of cement, 10 to 30 parts of silica fume, 5 to 20 parts of fly ash, 80 to 150 parts of aggregate, 0.1 to 2 parts of slaked lime, 5 to 25 parts of steel fiber, 1 to 5 parts of a water reducing agent, 0.05 to 0.5 part of a retarder, 0.01 to 0.2 part of a coagulant and 10 to 30 parts of water. The super-early-strength type ultra-high performance concrete has the characteristics of super early strength, ultrahigh later strength, ultrahigh durability, controllable setting time, excellent working performance and the like, and has important practical value in various emergency repair projects and winter construction projects. The invention further discloses a preparation method of the super-early-strength type ultra-high performance concrete, wherein the preparation method is simple, easy to operate, easy to control preparation conditions and low in requirement for production equipment, and is easy to achieve industrial production .
本发明公开了一种超早强型超高性能混凝土及其制备方法，属于建筑材料技术领域。按重量份计，该超早强型超高性能混凝土包括以下组分：水泥50‑100份、硅灰10‑30份、粉煤灰5‑20份、集料80‑150份、熟石灰0.1‑2份、钢纤维5‑25份、减水剂1‑5份、缓凝剂0.05‑0.5份、促凝剂0.01‑0.2份、水10‑30份。本发明的超早强型超高性能混凝土具有超早强、后期强度超高、超高耐久性、凝结时间可控、工作性能优异等多种特性，在各类抢修工程、冬季施工工程中具有重要的实用价值。本发明还公开了上述超早强型超高性能混凝土的制备方法，该制备方法简易、操作简便、制备条件容易控制，对生产设备要求较低，是一种容易实现工业化生产的方法。
