Abstract
U ovom radu provedeno je određivanje topline hidratacije industrijskog portland cementa, CEM I 42,5 R bez dodatka i uz dodatak otpadnog ambalažnog stakla različite finoće mliva (<45 µm i 125-250 µm). 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 ambalažnog stakla bio je 10, 20 i 30 mas. %. Toplina hidratacije, brzina oslobađanja topline i stupanj proreagiranosti za uzorke cementnih kompozita bez dodatka i s različitim dodatkom otpadnog ambalažnog stakla izračunati su pomoću računalnog programa „Hidratacija cementa“. Ukupno oslobođene topline do 48 sati hidratacije ukazuju da se povećanjem udjela otpadnog ambalažnog stakla registriraju manje vrijednosti toplina hidratacije i stupnja proreagiranosti kao i pojava krivulje maksimalne brzine hidratacije u kasnijim vremenima hidratacije. Finoća mliva otpadnog ambalažnog stakla neznatno utječe na ukupnu toplinu hidratacije kao i na stupanj proreagiranosti. Međutim rezultati ukazuju na odgađanje hidratacije korištenjem frakcije s većom veličinom čestica otpadnog ambalažnog stakla. Određene su funkcijske ovisnosti ukupno oslobođene topline i vremena pojave maksimalne hidratacije o udjelima otpadnog ambalažnog stakla za različite finoće mliva (<45 µm i 125-250 µm).
Abstract (english)
In this study the heat of hydration of the industrial Portland cement CEM I 42.5 R without addition and with the addition of waste container glass with different fineness of grind (<45 micron sand 125-250 microns) 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 V/C = 0.5, and water-solid ratio, V/K = 0.5. The content of waste container glass was 10, 20 and 30 wt. %. The heat of hydration, heat release rate and hydration degree for samples of cement composites without the addition and the addition of a variety of waste container glass were calculated using the computer program „Hidratacija cementa“. Total heat released until 48 hours hydration indicate that increasing the content of waste container glass 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. The fineness of grind waste container glass slightly affects the total heat of hydration as well as the hydration degree. How ever the results indicate a more delay in hydration using the fractions with higher particle size of the waste container glass. Functional dependences of released heat and the time of appearance of hydration maximums for samples with different content of waste glass with various fineness of grind (<45 micron sand 125-250 microns) were also determined.
