高性能混凝土作为一种新型高技术混凝土,能在大幅度提高普通混凝土性能的基础上,具有良好的耐久性。另外高性能混凝土一般是以“高强高性能混凝土”的形式提出的,中等强度的高性能混凝土的研究及应用较少,如果能实现中等强度普通混凝土的高性能化,将会产生重要的技术经济意义。本文以国内某电厂冷却塔工程为例,浅谈高性能混凝土的应用。该电厂地下水对混凝土的腐蚀为强等级腐蚀,冬季最低温度可达零下10℃,因此对混凝土的抗渗、抗冻等耐久性指标提出了更高的要求。
High-performance concrete as a new type of high-tech concrete, can greatly improve the performance of ordinary concrete, has good durability. In addition, high-performance concrete is generally proposed in the form of “high-strength high-performance concrete”. The research and application of medium-strength high-performance concrete is rare, and if it can achieve the high performance of medium-strength ordinary concrete, Technical and economic significance. In this paper, a domestic power plant cooling tower project as an example, on the application of high performance concrete. The power plant groundwater corrosion of concrete is a strong level of corrosion, the minimum temperature in winter up to minus 10 ℃, so the concrete impermeability, antifreeze and other durability indicators put forward higher requirements.
