Vliv vlhkosti na fyzikálně mechanické vlastnosti historických zdících materiálů

Abstract

Defects and faults are still quite important issues when dealing with historical buildings nowadays. The main structural elements of theese are bricks which are subjects to degradation processes due to moisture and static stress. The goal of this thesis is to identify and compare the physical and mechanical properties of selected elements of brick exposed to different temperature and humidity conditions. Theoretical part is concerned with features of masonry units and effects of moisture on the structure including the identification of selected defects and faults. The focus of experimental part is evaluation of the properties of masonry units, using practical tests IN SITU and laboratory measurements of selected historical building Löw-Beer Villa in Brno.
