Analysis of chemical structure and characteristics of building materials based on element chemistry

Abstract

Elements in accordance with a certain proportion and spatial arrangement constitute the microstructure of the building materials, which lead to a specific property and function in the macro. From the perspective of element chemistry, we divide common building materials into three categories: silicon-based building materials, carbon-based building materials and iron-based building materials. Then, with the knowledge of valence electron structure and electronic configuration, we systematically expound the three-element building materials system. According to that division mode, we explain the microstructural causes and macroscopic properties of the three-element building materials system through the valence bond theory, so as to provide references for the development and application of building materials.
