Durability research of high performance concrete and its application in engineering

Abstract

With the development of modern science and technology, the application of concrete is more and more extensive, and the performance of traditional concrete has been difficult to meet the high requirements of engineering. All countries in the world are committed to seeking concrete with good construction performance, good durability, long service life and other advantages. Durability is the main design index of high performance concrete (HPC), so this paper studies and analyzes the main factors affecting the durability of HPC and the technical ways to improve the durability of concrete. The main internal factors affecting the durability of HPC are high water consumption and unstable hydrate in cement. External factors are various environmental conditions and protective measures of concrete structures. The technical ways to improve the durability of concrete mainly include reasonable structural design, reasonable concrete mix ratio, adding mineral admixtures and admixtures, reliable construction technology and regular maintenance. In the future, high-performance concrete should develop in the direction of economic green, and try to be environmentally friendly and recyclable while meeting the strength needs.
