Studies of changes in the structure of vermiculite as a filler of building materials by the method of electron microscopy

摘要

In this article, construction materials are considered, which are used as a lightweight aggregate for concretes and mortars as well as for thermal insulation designs. Particular attention is paid to materials based on expanded vermiculite. The methods of using vermiculite in construction are analyzed. The study is carried out by electron microscopy of vermiculite crystals burnt traditionally and treated with chemical solutions (fired at 400 ° C). Based on the above study, the developed method for baking vermiculite can be considered the most suitable for technological parameters and operational requirements for use in the construction industry.
