【 摘 要 】

In the era of rapid development in the construction industry, particular attention is focused on harmless and natural materials. Some of the best materials for building masonry walls are sand-lime products. Silicates are obtained from a mixture of quartz, sand and a small amount of water. They emerge as a result of the hydrothermal treatment conducted under high pressure and at a temperature of app. 203 °C. Silicates were modified of different kinds of aggregates, glass or plastics, and the content of dry ingredients was changed because of this fact. The paper describes the studies where the combination of diabase aggregate and chalcedonite meal was used. Microstructure of the products was analyzed with the use of mercury intrusion porosimetry, SEM and XRD methods. Variable content of chalcedonite meal changes the internal structure and the physico-chemical properties.
