Abstract
U ovom radu provedeno je određivanje specifične električne provodnosti cementnih pasti, bez dodatka i uz dodatak 20 mas. % otpadnog ambalažnog stakla različite finoće mliva (<45 µm, 125-250 µm, 250-500 µm). Mjerenja su provedena u termostatu pri 20 °C i pri vodocementnom, V/C = 0,5 i voda/kruto omjeru, V/K = 0,5. Sve dobivene krivulje ovisnosti specifične električne provodnosti o vremenu hidratacije cementnih pasti imaju sličan grafički oblik s naglašenim vrhom maksimalne provodnosti. Vrijeme početka vezivanja za pojedini tip cementa odgovara vremenu pojave maksimalne specifične provodnosti. Iz rezultata se može zaključiti da dodatak otpadnog ambalažnog stakla uzrokuje pad vrijednosti specifične električne provodnosti. Finoća mliva nema značajan utjecaj na vrijeme pojave i vrijednost maksimalne električne provodnosti. Također, dodatak otpadnog stakla ne utječe na početak vezivanja cementnih pasti. Budući da su za svaki uzorak provedena po dva mjerenja, uočena je dobra ponovljivost mjernih podataka.
Abstract (english)
In this paper, the determination of the specific electrical conductivity of the cement pastes was carried out without the addition and with addition of 20 wt. % of waste container glass with different fineness (<45 µm, 125-250 µm, 250-500 µm). The measurements were carried out in a thermostat at 20 °C and at the water/cement ratio, W/C=0.5 and water/solid ratio, W/S=0.5. All obtained curves of specific electrical conductivity dependence on the hydration time of the cement paste have a similar graphical shape with a pronounced peak of maximum conductivity. The start of binding time for a particular type of cement corresponds to the time of occurrence of maximum specific conductivity. From the results it can be concluded that the addition of waste container glass decreases specific electrical conductivity values. The different particle size of waste glass does not have a significant influence on the time of appearance and the value of maximum electrical conductivity. Also, the addition of waste glass does not affect the start of binding time of cement pastes. Since two measurements were performed for each sample, good repeatability of metric data was observed.
