Concrete crack rapid repairing material and construction technology thereof
The invention provides a concrete crack rapid repairing material and a construction technology thereof, and the concrete crack rapid repairing material comprises the following components by weight: 40-70 parts of high sulfur fly ash, 10-25 parts of an alkaline activator, 0-20 parts of an auxiliary cementing material, and 10-20 parts of water. The high-sulfur fly ash is selected as a raw material, ettringite generated by hydration reaction of the high-sulfur fly ash in an alkaline environment has a certain expansion effect, and the content of SO3 in the high-sulfur fly ash is adjusted, so that the prepared rapid repairing material has good mechanical properties and expansibility, cracks caused by contractility of the raw material are repaired, and the service life of the rapid repairing material is prolonged. And the prepared rapid repairing material is tightly combined with a peripheral base body, and the mechanical property is good. The invention provides a concrete crack rapid repairing material and a construction technology thereof, and solves the problem of large volume deformation in an existing alkali-activated material.
本发明提供一种混凝土裂缝快速修补材料及其施工技术，由以下重量份数的成分组成，40‑70份高硫粉煤灰、10‑25份碱性活化剂、0‑20份辅助胶凝材料、10‑20份水。在原料上选择高硫粉煤灰，利用其在碱性环境下水化反应生成钙钒石而具有一定的膨胀效果，并且通过调节其中的SO3的含量，使制备的快速修补材料具有良好的力学性能与膨胀性，修复原材料因自身的收缩性出现的裂缝，并且本发明制备的快速修补材料与周边基体结合紧密，力学性能好。本发明提供一种混凝土裂缝快速修补材料及其施工技术，解决目前碱激发材料中体积变形较大的问题。
