| 摘 要： | 超早强修补水泥混凝土的主要技术难点是在满足施工要求的前提下，使水泥混凝土在尽可能短的时间内达到通车要求，同时使新旧混凝土具有良好的整体性。本文通过室内试验研究，成功地解决了在普通混凝中掺入超早强修补剂，使修补水泥混凝土路面在数小时内达到通车要求，并大幅度降低了修补混凝土脆性高的技术缺陷，同时本文从机理上分析了修补水泥混凝土产生超早强及低脆性能的原因。 |
| 关 键 词： | 超早强修补强 脆性 机理分析 水泥混凝土 |

| Abstract: | To meet the need of construction, the main technical problem of super rapid strength mending concrete is how to enable the transportation in service as soon as possible and make both the old and new concrete bear good intergrity. Through lab testing and researching, this paper has successfully solved this technical problem. By mixing mending agent with ordinary concrete, the mended highway can be in use within several hours and the brittleness is also dramatically decreased. Besides, the reasons that mending concrete has the ability to generate super-rapid strength and low brittleness from the mechanism are analyzed. |
| Keywords: | super-rapid strength mending agent concrete brittleness mechanism analysis |
