The Influence of the Quality of Brick Firing on Their Calcium Diffusion Capacity and Biodegradation Potential—A Preliminary Study

Abstract

: The diffusion of calcium ions Ca 2+ in aquatic solutions (10 g/l) was measured for two brick samples from a region in Bohemia (Vysok é M ý to, Holešov-Žopy). The experiment was performed under laboratory conditions at the ambient temperature of 20 ± 2 ◦ C for a period of 240 h. The bricks were cut into three depth layers. The calcium concentrations were analyzed chelatometrically. The biodegradation potential of the individual layers was also studied. The results indicated that the depth and quality of firing are of importance regarding the transport of calcium, and they affect the success of bio-colonization.
