The Influence of Clay Structures to the Hygrothermal Component of the Indoor Environment

Abstract

In this article, research on the sorption properties of clay materials in comparison with commonly used building materials is published. The topic is mainly focused on the dynamic sorption properties and their influence on the relative humidity in the indoor environment. The results of comparisons of clay structures, rammed earth panels, clay plaster, and unburned bricks, with commonly used building materials, concrete, lime plaster, and gypsum board are examined. Statistically evaluated results in the form of confidence intervals are presented and the rate of dynamic sorption is analyzed. It is clear from the results that clay materials have a positive effect on the rapid adsorption and desorption of air moisture in the interior of buildings. However, there are many variables, band not every clay material has such excellent sorption properties.

Development of Clay-Composite Plasters Integrating Industrial Waste

“…This surge in interest can be attributed to several key factors that make clay houses an appealing choice. However, an essential characteristic is that using natural, non-toxic materials in the building process significantly reduces the risk of indoor air pollution and other health hazards, making clay homes a safer and ecofriendlier option [22]. One important parameter that characterizes the indoor air quality is ozone (O 3 ).…”

“…Clay plasters are known for their eco-friendly and sustainable characteristics [3,13,[22][23][24]36] but also have certain drawbacks [13,37]. One of the main concerns is the shrinkage during the drying process.…”
