随着工程建设的发展及国家进一步的改革开放,混凝土结构在我国各项工程建设中得到迅速的发展和广泛的应用。混凝土结构施工主要特点是取材便捷,可以在多种建筑结构中使用,混凝土结构在民用建筑、高层建筑、大跨度的公共建筑和工业建筑、桥梁、水利、地下结构等工程中都具有广泛应用。混凝土的硬化源于水泥的水化作用,影响水泥水化和强度的因素也影响混凝土强度。环境温度和湿度对水泥的水化作用具有显著影响,因此为保证混凝土强度需要从混凝土成型后一定时间以内对混凝土开始养护。本文以混凝土施工现场实际为例,论述混凝土养护对混凝土强度的影响。
With the development of engineering construction and the further reform and opening up of the country, the concrete structure has been rapidly developed and widely used in all kinds of engineering construction in China. The main features of the construction of concrete structure is easy access to materials, can be used in a variety of building structures, concrete structures in civil buildings, high-rise buildings, large-span public buildings and industrial buildings, bridges, water conservancy, underground structures and other projects have a wide range of applications. The hardening of concrete is due to the hydration of the cement, and the factors that affect the hydration and strength of the cement also affect the strength of the concrete. Ambient temperature and humidity have a significant effect on the hydration of cement, so to ensure the strength of concrete, the curing of concrete needs to be started within a certain period of time after the concrete is formed. In this paper, the concrete construction site as an example, discusses the impact of concrete curing on the strength of concrete.
