摘要
养护对混凝土的水泥水化有重大的影响,养护的温度和湿度是影响水泥水化的关键因素,早期良好的养护能减少高性能混凝土的自收缩。分析了高性能混凝土组成结构上的特点并阐述了高性能混凝土在养护上的特点。为了更好地应用高性能混凝土,一个重要方面就是通过适宜的养护方法获得高性能混凝土的全面性能。为了获得所期望的混凝土强度和耐久性性能,充分的养护显得极为重要。
It was tried to explain the significant influence of curing on cement hydration of concrete. The temperature and humidity of curing were the key factor that effected cement hydration. A good early curing could reduce autogenous shrinkage of high performance concrete. It was analysed structural characteristics of composition of high .performance concrete and explained the curing features of this concrete. Thus one of the critical aspects for the successful usage of high performance concrete would be knowing how to cure it to achieve its full performance. It had long been recognized that adequate curing was to obtain the desired strength and durability properties of concrete.
