混凝土的极限强度主要取决于水泥水化的程度。水是水泥水化的必要组分,由于水化作用进程缓慢,对混凝土进行必要的养护,防止混凝土早期硬化阶段的水分损失,是保证混凝土在规定龄期内达到设计强度要求、防止产生收缩裂缝的关键。因此养护在混凝土施工中是不可忽视的重要环节。
The ultimate strength of concrete depends mainly on the degree of cement hydration. Water is an essential component of cement hydration. Due to the slow hydration process, the necessary maintenance of concrete to prevent the early hardening of concrete moisture loss is to ensure that the concrete reaches the design strength requirements within the specified age to prevent shrinkage cracks key. Therefore, conservation of concrete construction can not be ignored in an important part.
