Originální abstrakt

The protection of building structures and elements from the effects of moisture is currently a topical and discussed topic and this issue is also related to development of hydrophobized ceramic masonry elements with reduced water absorption.The quality and efficiency of the hydrophobic treatment is assessed primarily by monitoring the capillary absorption of the hydrophobized ceramic body and reducing the capillary conductivity (reducing the capillary elevation of moisture).The paper focuses on the more detailed physical study of the hydrophobic treatment of ceramic masonry blocks using laboratory methods, in particular the measurement of the contact angle and surface energy. With these measurements, it is possible to precisely specify the surface properties of individual ceramic masonry elements treated by hydrophobic treatment and thus accurately express the quality of the surface treatment. Based on the results was determined the dependence between capillary absorption and surface energy.
