Abstract
Materials containing thermally treated clay minerals are well known for their pozzolanity, i.e. ability to react with calcium hydroxide to cementing compounds. Finely ground ceramics have been used as pozzolan since ancient times and nowadays they again attracts attention because of the current effort to utilize waste as secondary raw material. Contrary to other pozzolans (fly ash, metakaolin etc.) ceramics contain not only a reactive phase but also a certain amount of crystalline minerals which do not take part in the hydration process. The paper deals with finely ground ceramic powder generated during production of brick blocks.
