New cement composites

Abstract

U ovom radu istraživan je utjecaj klorida alkalijskih metala, zemnoalkalijskih metala i klorida prijelaznih elemenata na vrijeme početka vezanja aluminatnog cementa (AC) s ciljem priprave novih cementnih kompozita. Korišten je komercijalni aluminatni cement (AC) Istra 40, proizvođača "Istra Cement International" iz Pule, Hrvatska. Vrijeme početka vezanja određivano je standardnim Vicatovim testom.This paper examines the influence of alkali metals chlorides, alkaline earth metals chlorides and chlorides of transition elements on setting time of the calcium aluminate cement (CAC) with purpose of manufacturing new cemente composites. Commercial calcium aluminate cement (CAC) Istra 40, manufactured by "Istra Cement International" from Pula, Croatia, was used. Setting time of the calcium aluminate cement was determined by standard Vicat test
