Abstract
U ovom radu provedeno je određivanje topline hidratacije sustava portland cementa CEM I i 0,3% plastifikatora ˝Aquarex directa˝ bez dodataka te uz dodatak otpadne građevinske opeke. Određivanje topline hidratacije provedeno je do 48 sati hidratacije uporabom diferencijalnog mikrokalorimetra pri 20 ºC i uz vodocementni omjer, V/C = 0,5 te uz voda-kruto omjer, V/K = 0,5. Maseni udjeli otpadne građevinske opeke iznosili su 5-30 mas.%. Pomoću računalnog programa ˝Hidratacija cementa˝ izračunate su topline hidratcije, brzina oslobađanja topline i stupanj proreagiranosti za uzorke cementne paste bez dodataka i s različitim dodatkom otpadne građevinske opeke. Ukupno oslobođene topline do 48 sati hidratacije ukazuju da se s povećanjem udjela otpadne građevinske opeke registriraju niže vrijednosti topline hidratacije, brzine oslobađanja topline i stupanj proreagiranosti. Na osnovi izračunatih parametara određen je najpovoljniji matematički opis ovisnosti udjela dodataka i izračunatih hidratacijskih parametara.
Abstract (english)
This study is conducted to determine the heat of hydration of Portland cement CEM I and 0.3% ˝Aquarex direct˝ plasticizer system with and without the addition of the building brick waste. Determining the heat of hydration was conducted with up to 48 hours of hydration with the application of a differential microcalorimeter at 20 ºC, with water-cement ratio, W/C=0.5 and water- solids ratio, W/S=0.5. Mass fractions of the building brick waste were 5-30 wt.%. Using the ˝Cement hydration˝ computer program it was able to calculate the heat of hydration, the rate of heat release and the degree of it was hydration for cement paste samples without additions and with diverse additions of building brick waste. Total released heat with up to 48 hours of hydration points that with the increased ratio of building brick waste, the lower values of the heat of hydration, the rate of heat release and the hydration degree are recorded. Based on the calculated parameters, it is possible to the most optimal mathematical description of interdependency between ratio of additions and calculated hydration parameters.
