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.
:对波希米亚地区(Vysok M ý to, Holešov-Žopy)的两块砖样品测量了钙离子ca2 +在水溶液中的扩散(10 g/l)。实验在实验室条件下进行，环境温度为20±2◦C，时间为240 h。砖被切割成三层深度。用螯合滴定法测定钙浓度。研究了各层的生物降解潜力。结果表明，烧制的深度和质量对钙的运输有重要影响，并影响生物定植的成功。
