高性能混凝土是一种新型高技术混凝土,是在大幅度提高普通混凝土性能的基础上采用现代混凝土技术制作的混凝土。它以耐久性作为设计的主要指标,针对不同用途要求,对下列性能重点予以保证:耐久性、工作性、适用性、强度、体积稳定性和经济性。为此,高性能混凝土在配置上的特点是采用低水胶比,选用优质原材料且必须掺加足够数量的矿物细掺料和高效外加剂。
High-performance concrete is a new type of high-tech concrete, which is made by using modern concrete technology on the basis of greatly improving ordinary concrete performance. Its durability as a major indicator of design, according to the requirements of different uses, to ensure the following key performance: durability, workability, adaptability, strength, volume stability and economy. To this end, high-performance concrete in the configuration is characterized by the use of low water glue ratio, the selection of high quality raw materials and must be mixed with a sufficient amount of fine mineral admixtures and additives.
