Application and Verification of Physical - Mechanical Properties of Modified Clay Plaster by Silicates

摘要

Clay plasters have been used extensively in the past. Later, these plasters were replaced with more modern materials. In recent years, however, they have come back and are being used primarily for new constructions. The interest in ecological constructions and natural materials was significantly influenced not only by experts but also by ordinary users. A significant disadvantage of clay plasters is poor durability in the exterior environment and in contact with water in the liquid state where the part of the clay product is leached. The paper deals with the modification of clay plasters with silicate-based hydrophobic agents. The aim of this experiment is to improve the durability of these plasters and to extend their application both indoors and outdoors while maintaining typical advantageous properties.
