Abstract

Proizvodnju cementa prate brojni problemi i zahtjevi, od onih za povećanje učinkovitosti do onih za poboljšanje trajnosti i svojstava. Djelomičnom ostvarenju tih ciljeva pridonose aditivi za beton, tako da danas gotovo nema izvedbe nekog betonskog objekta bez primjene djelotvornih aditiva. To se posebno odnosi na one betonske kompozite za koje su postavljeni visoki kriteriji kakvoće, tj.za one od kojih se traže posebna svojstva. Posebnu pažnju kod odabira pojedinog aditiva treba obratiti na njegov volumni udio tj. doziranje i njegov utjecaj na hidrataciju cementnog kompozita.

Abstract (english)

The manufacture of cement is accompanied by a number of problems and requirements, from those aimed at increasing efficiency to those intended to improve the durability and performance of cement. Concrete additives contribute to partial realization of these objectives, so that nowadays there is almost no performance of a concrete facility without the use of effective additives. This is especially true for those concrete composites that are set with high standards of quality and specific properties. When selecting additives, the volume share, i.e. the dosage, and its effect on hydration of the cement composite are two things special attention should be paid to.
