Research on the Application of Environmentally Friendly Intelligent Materials in Civil Engineering

Abstract

This paper mainly focuses on the study of environmentally friendly intelligent materials. In this paper, optical fiber, intelligent concrete, piezoelectric materials, shape memory alloy (SMA), ecological cement materials are introduced. The principle, characteristics and application of these four kinds of environmental friendly intelligent materials in civil engineering are introduced in detail. The research shows that these materials have many advantages at the same time. First of all, for optical fiber sensing intelligent concrete, its advantages are high sensitivity and high flexibility, and resistance to high pressure and high temperature, so it is suitable for detecting the load inside the concrete. Secondly, SMA has the characteristics of high strength and high flexibility, which can be used for strengthening buildings and other aspects, effectively extending the service life of concrete. Piezoelectric materials have the characteristics of fast response speed and high precision, which can be used for safe control and evaluation of material repair ability. Finally, as an energy-saving and environmentally friendly intelligent material, the development of ecological cement materials helps to reduce carbon dioxide emissions and better protect the environment. At the same time, the development direction of environmentally friendly intelligent materials in the future is given to provide reference for its application in civil engineering.
