The central part of the Czech Republic, called the Bohemian-Moravian Highlands, is well known for its historical mining activities, especially silver ores in the Jihlava district, dating back to the medieval period. Evidence of historical mining is still visible in the local landscape. This article analyses water samples collected at various locations within the so-called Pekelska stola (Hollen Stollen), near the town of Strbrne Hory. The mining activities in this adit have been documented since the 17th century; ...

The southern part of the Vysocina region (Bohemian-Moravian Highlands), defined by the surroundings of towns Telc and Slavonice, has been associated with the use of local crystalline limestones – marbles, since the Middle Ages. These marbles were burned to produce lime that was used not only for traditional masonry, but also for renders and plasters. Nowadays, analyses of preserved fragments of incomplete burned marble or binder-related particles in historical objects represent a valuable source for the rediscov...

THE EFFECT OF COAL ADDITIVE TYPE ON PROPERTIES OF CEMENT PASTES

(STEF92 Technology, 2020-09-20, Jaroslav Pokorný, Radek Ševčík, Jiří Šál)

Show more

Concrete represents a traditional building material that is commonly applied due to its unique properties, like relatively high compressive strength and long-term durability. Such properties are gained because of its composition consisting of aggregate and cement. The usage of Portland cement, a worldwide available binder with annual production exceeding 4.6 billion tons, brings several environmental loads. One of them is releasing of an important amount of greenhouse gases into the atmosphere. Another environment...
