Abstract

Ujawniono dodatek do zapraw i betonów wykonywanych z cementów powszechnego użytku jak również cementów specjalnych, poprawiający wytrzymałość mechaniczną stwardniałego materiału oraz redukcję ilości cementu w mieszance, o właściwościach przyspieszających wiązanie i twardnienie betonu. Dodatek charakteryzuje się tym, że zawiera w składzie perlit ekspandowany w zakresie nie mniejszym niż 90% wagowych, o uziarnieniu 0,1 - 10 µm, uzyskany korzystnie w procesie mielenia dowolnej jego frakcji ziarnowej, korzystnie przed mieleniem sprasowany; substancje pomocnicze, przeciwdziałające zbrylaniu, przyspieszające wiązanie i twardnienie cementu, w zakresie nie większym niż 10% wagowych.An additive to mortars and concretes made of common cements as well as special cements has been disclosed, improving the mechanical strength of the hardened material and reducing the amount of cement in the mixture, with properties that accelerate the setting and hardening of concrete. The additive is characterized by the fact that it contains expanded perlite in the range of not less than 90% by weight, with a grain size of 0.1 - 10 µm, preferably obtained in the process of grinding any of its grain fractions, preferably pressed before grinding; auxiliary substances that prevent caking and accelerate the setting and hardening of cement, in the range not exceeding 10% by weight.
