Abstract
Chemical building material has become the fourth largest building material after wood, cement and steel. With the advantages of low energy consumption, environmental protection, low cost, good stability, toughening and strengthening, etc., it has been applied in more fields. In this paper, by taking the material systems of building plastics, building coatings, building waterproofs, and thermal insulation material as the objects of study, SEM technology was adopted to study their microstructures and properties. The study found that the incorporation of mineral materials can improve the properties of building materials in different degrees, and the calcium carbonate can be well combined with the building plastic door and window materials; the combination of kaolin, mica, barium sulfate, and wollastonite with waterproof coatings endows the waterproof coating with good overall performance; illite particles and the waterproof material matrix are ideally cemented, with fuzzy interface, and the overall morphology is presented in the felsitic texture; the interface of vitrified microbeads thermal insulation mortar is not obvious, indicating better thermal insulation effect.
