高速铁路高性能混凝土配合比优化及性能研究

高性能混凝土是大量提升普通混凝土的性能,选择用现代混凝土技术进行配比的一种新型高技术混凝土,具有杰出的耐久性,这是它高性能的特点之一,也是主要的设计指标。高性能混凝土是指在质量优秀的水泥和骨料等原材料中加入充足的矿物活性细掺合料和高性能外加剂。在高速铁路的施工中,利用高性能混凝土可以减少施工后的养护成本,实现可持续发展的目标。

High-performance concrete is a new type of high-tech concrete, which is based on a large number of ordinary concrete performance. It has outstanding durability, which is one of its high-performance characteristics and the main design index. High-performance concrete refers to the combination of sufficient mineral active fine admixtures and high-performance admixtures through excellent raw materials such as cement and aggregates. In the construction of high-speed railway, the use of high-performance concrete can reduce the maintenance cost after construction and achieve the goal of sustainable development in the world.
