Abstract

An advantage of this approach is that tiles made of heterogeneous natural materials can be built into urban objects of different architecture and energy profiles. Their right position in a room would enable natural ventilation based on changes in the air composition that would reduce the exchange of air with the environment, reduce heating costs during the winter and provide cooling during the summer while at the same time maintaining relatively similar air composition. The research showed that sand and ceramic clay enable quicker drying of the sample in comparison to bentonite clay, polyphosphate and a plasticizer enable.

Highlights

Today there are many different types of material used during construction of technical facilities and buildings [1,2]
The greatest release of moisture was determined for the material from series 1, since it contained the greatest amount of ceramic clay with a small addition of sand
In the case of the composite mixture from series 2, the addition of greater amounts of sand and wood chips should facilitate the removal of the water from the material

Summary

Introduction

Today there are many different types of material used during construction of technical facilities and buildings [1,2]. Bentonite clay as one of them is very important for manufacturing of building materials [3]. The physicochemical properties of bentonite clay are commonly modified by addition of polymers in order to improve its characteristics [4,5]. Recent studies have been trying to improve and apply the natural materials with modified properties for both cooling and solar heat storage. This paper will analyze the influence of the composition of tiles including ceramic clay, bentonite clay, plasticizers, wood chips, and zeolite on the processes of adsorption, i.e. moisture desorption. The experiment included the process of drying – desorption of moisture from raw tiles until it reaches a constant mass. The process of desorption over a period of 2 hours was studied on a sample of tiles resoaked in demineralized water
