普通混凝土、高强混凝土与高性能混凝土

混凝土100多年来的应用与发展过程也是强度与性能不断提高的过程。按其强度和性能提高划分其发展过程，混凝土可以简单地划分成普通混凝土、高强混凝土和高性能混凝土。要提高混凝土结构的耐久性，延长使用寿命，最重要的是提高混凝土强度和性能，故高性能混凝土成为今后混凝土技术发展的方向。

ORDINARY CONCRETE,HIGH STRENGTH CONCRETE AND HIGH PERFORMANCE CONCRETE

The process of application and development for concrete over 100 years is the process of strength and performance to be increased continually. According to increasing the strength and performance to differentiate its development process, the concrete can be divided simply into the ordinary concrete, high strength concrete and high performance concrete. In order to increase the durability of the concrete structure and extend the useable life, it is the important thing to increase the concrete strength and performance. So the high performance concrete will be the direction of technology development for the concrete in the future.
