This paper analyzes and explains the evolution of audio language in terms of content, technology, copyright, and other aspects, in order to sort out the development context of audio language and explore its communication laws and trends. In the development process of audio language, emphasis should be placed on intelligently presenting audio information, building an audio ecological closed loop, and collaborating to improve market rules to achieve more comprehensive and efficient progress.

Recently, the use of sustainable materials has gained increasing attention and recognition, especially in the construction industry. As the main component of concrete, ordinary Portland cement (OPC) is undoubtedly one of the most commonly used building materials in the world. However, the manufacture of OPC is accompanied by environmental and ecological problems such as the release of carbon dioxide. According to estimates, about 5%-8% of the world think that carbon dioxide emissions come from the OPC industry, so it is urgent to use fly ash, tailings, slag and other industrial solid waste to produce cement instead of ordinary Portland cement.This article summarizes the achievements of the predecessors and outlines the influence of different iron tailings and iron tailings content on the mechanical properties and durability of concrete.
