Abstract
U ovom radu istraženo je djelovanje komercijalno dostupnog ubrzivača pod nazivom Cementol® Omega F- conc na brzinu vezanja i očvršćivanja Portland cementa. Ispitan je i utjecaj dodatka ubrzivača na smanjenje količine vode potrebne za postizanje standardne konzistencije, te je potvrđeno djelovanje ovog aditiva i kao superplastifikatora. Izmjerene čvrstoće na tlak Portland cementa i Portland cementa s dodatkom komercijalnog ubrzivača pokazuju da dodatak ubrzivača pospješuje razvoj ranih čvrstoća, dok su čvrstoće nakon 28 dana hidratacije manje od referentnog uzorka Portland cementa pripravljenog bez dodatka ubrzivača. Kalorimetrijskim mjerenjem praćen je tijek hidratacije, te je ustanovljeno da dodatak Cementola od 3% odgađa reakciju silikatnih faza.
Abstract (english)
In this paper, the activity of a commercially available accelerating admixture called Cementol® Omega F- conc was investigated in terms of bonding and hardening of Portland cement. The influence of adding the accelerating admixture to the reduction in the amount of water required to achieve standard consistency was also tested, and the action of this additive as a superplasticizer as well was confirmed. The measured compressive strengths of Portland cement and Portland cement with the addition of a commercial accelerating admixture show that the addition of accelerating admixture enhances the strength development at early ages, while the strength development after 28 days of hydration is less than the reference sample of Portland cement prepared without the addition of accelerating admixture. The hydration flow was followed by the calorimetric measuring, and it was found that the addition of 3% Cementol delays the reaction of silicate phases.
