高性能混凝土(High performance concrete,简称HPC)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,其具有耐久性、工作性、适用性、强度、体积稳定性和经济性等特性。作为现代化建设不能或缺的一项建筑材料,混凝土同时也是建筑材料中用量最大的。伴随不断加快的现代化进程,混凝土的用量还在不断的增多,在社会要求工程质量不断提高的大背景之下,作为新型的建筑材料,高性能的混凝土己经在路桥的施工中得到了广泛的应用。本文对高性能混凝土的机理和特征做了简要的介绍,并对其在公路桥梁施工中的应用作了大致的论述。
High performance concrete (HPC) is a kind of concrete made by modern concrete technology based on greatly improving the performance of normal concrete. It has the characteristics of durability, workability, applicability, strength, volume stability and economy characteristic. As an indispensable building material for modernization, concrete is also the largest amount used in building materials. With the accelerating modernization process, the amount of concrete is still increasing. Under the background that the society requires the engineering quality to be continuously improved, as a new type of building material, high-performance concrete has been widely used in the construction of road and bridge application. This paper gives a brief introduction of the mechanism and characteristics of high performance concrete, and discusses its application in highway bridge construction.
