Abstract
U radu je ispitivan utjecaj dodatka aditiva i zeolita zasićenog cinkom na ranu hidrataciju portland cementa pri 20 ℃ i vodocementnom omjeru, V/C=0,5 i voda/kruto omjeru, V/K=0,5. Pomoću računalnog programa određena je toplina hidratacije, brzina oslobađanja topline i stupanj proreagiranosti za uzorke bez i uz dodatak superplastifikatora te uz dodatak 0, 5, 10, 15, 20, 25 i 30 mas. % zasićenog zeolita. Također je provedena kinetička analiza eksperimentalnih podataka stupnja proreagiranosti pomoću računalnog programa Mathcad. Iz rezultata je vidljivo da uvođenjem dodataka u reakcijski sustav cement – voda dolazi do promjene termonaponske veličine tijekom hidratacije cementnih pasti. Povećanjem udjela zasićenog zeolita u uzorku, brzina oslobađanja topline i stupanj proreagiranosti pokazuju niže vrijednosti. Dodatak superplastifikatora i zasićenog zeolita u portland cementu utječe na kinetiku hidratacije cementa, što je vidljivo iz kinetičkih parametara.
Abstract (english)
This work examines the influence of addition of admixture and zeolite saturated with zinc on early hydration of Portland cement at 20 ℃ and water/cement ration, w/c = 0.5 and water/sold ratio, w/s = 0.5. Heat of hiydration, the rate of heat released and the degree of hydration are determined by a computer program for samples without and with the addition of superplasticizer and addition of 0, 5, 10, 15, 20, 25 and 30 wt.% saturated zeolite. Also, the kinetic anylis of experiments dana oft he degree of hydration was carried out using a computer program Matchcad. From the results it is apparent that introducing additive into the cement-water system will change the voltage during cement pastes hydration. By increasing the proportion of saturated zeolite int he sample, the rate of heat released and degree of hydration show lower values. The addition of superplasticizer and saturated zeolite to Portland cement affects the kinetics of cement hydration, as can be seen from kinetic parameters.
