Abstract
U ovom radu provedeno je određivanje topline rane hidratacije industrijskog portland cementa TECNOCEM bez dodatka i uz dodatak otpadnog hidratiziranog cementa. Određivanje topline provedeno je korištenjem diferencijalnog mikrokalorimetra tijekom prvih 48 sati hidratacije pri 20 °C i uz vodocementni omjer, V/C=0,5, odnosno voda-kruto omjer, V/K=0,5. Udjel otpadnog hidratiziranog cementa bio je 0, 5, 10, 15, 20, 25 i 30 mas. %. Toplina hidratacije, brzina oslobađanja topline i stupanj proreagiranosti za uzorke cementnih kompozita bez dodatka i s različitim dodatkom otpadnog hidratiziranog cementa izračunati su pomoću računalnog programa „Hidratacija cementa“, a dobivene vrijednosti su prikazane grafički pomoću računalnog programa Microsoft Excel. Ukupno oslobođene topline do 48 sati hidratacije ukazuju da se povećanjem udjela hidratiziranog cementa registriraju manje vrijednosti toplina hidratacije i stupnja proreagiranosti kao i pojava krivulje maksimalne brzine hidratacije u kasnijim vremenima hidratacije.
Abstract (english)
In this study the heat of hydration of the industrial Portland cement TECNOCEM without addition and with addition of waste hydrated cement was determined. Determination was carried out using a heat differential microcalorimetry during the first 48 hours of hydration at 20 °C and with a water- cement ratio W/C=0,5, and water-solid ratio,W/S=0,5. The content of waste hydrated cement was 0, 5, 10, 15, 20, 25 i 30 wt. %. The heat of hydration and the addition of a variety of waste hydrated cement were calculated using the computer program „Hidratacija cementa“ and the values are represented graphically using the computer program Microsoft Excel. Total heat released until 48 hours hydration indicate that increasing the content of hydrated cement register lower values of heat of hydration and hydration degree as well as the occurrence of the hydration maximum in the later times of hydration.
