Pointing at the outset of his work to importance of a thorough analysis of historic building that may supply the basis for its appropriate conservation or restoration, the author more widely deals with one of important parts of the said analysis, namely experimental investigations of binders, mortars, concretes and other building materials. Their samples taken from different parts of a historic building may be of utmost importance not only as an auxiliary material for exact dating of a given object, but also — and in several cases mainly — as an indication what kinds of materials are to be applied during conservation to avoid the dangerous and harmful for an object under conservation consequences of chemical and physical conflicts that may occur between the original materials and those used for conservation or resoration. Investigations carried out by the author within the antique area of the Black Sea coast have allowed him to make several findings and draw a number of conclusions of high methodic importance for archaeologists, conservators and art historians. Basing on investigations of mortars to be found in the antique buildings (e.g. a dwelling house, dating from the 6th century B.C., at Pantikapea on the Kerch Peninsula) he has authoritatively stated that in despite of conventionally adopted in archaeology views that no lime mortars were used in antiquity the mortars found there by him and his co-workers are the lime mortars in some instances filled with an addition of ground bricks.
W badaniach źródeł literatury przedmiotu autorzy artykułu ujawnili szereg kontrowersyjnych zagadnień związanych z procesami fizykochemicznymi zachodzącymi w systemie cementu portlandzkiego z dodatkiem włókna bazaltowego. W związku z tym przeprowadzono serię eksperymentów w celu zbadania właściwości włókna bazaltowego potraktowanego koloidalnym wodorotlenkiem glinu. Zaproponowano technologię wprowadzania włókna bazaltowego do mieszanki betonowej i przedstawiono analizę wyników eksperymentalnych.

While studying the research sources, the authors of the article investigated a number of issues concerning the physicochemical processes taking place in the Portland cement system with the addition of basalt fibre. A series of experiments was conducted to study the properties of basalt fibre treated with colloidal aluminium hydroxide, the technology of injection fibre into the concrete mixture was proposed and an analysis of the results of the experiment was presented.
