Abstract	U ovom radu ispitivan je utjecaj dodatka otpadnog ambalažnog stakla različitih frakcija na normalnu konzistenciju cementnih pasti. Ispitivanja su provedena na portland cementnim pastama uz dodatak stakla s udjelom 20 mas. % različitih frakcija (<45m, 125-250 m i 250-500 m) pri 24 °C i 1007 hPa. Uvođenjem otpadnog ambalažnog stakla u sustav cement-voda, reakcijski sustav se proširuje i postaje složeniji. Javljaju se nove interakcije u sustavu, a kao posljedica toga uspostavljaju se nove ravnoteže i ravnotežni sustavi. Početak vremena vezivanja za određenu vrstu cementa odgovara vremenu nastanka maksimalne specifične vodljivosti.Iz rezultata se može zaključiti da normalna konzistencija cementnih pasti ne ovisi samo o kemijskom sastavu cementa, nego i o specifičnoj površini cementnog praha, finoći mljevenja otpadnog ambalažnog stakla, vodocementnom faktoru i temperaturi. Dodatkom otpadnog ambalažnog stakla vrijednosti specifične električne provodnosti opadaju osim za najfiniju frakciju. Uz dodavanje finije i srednje fine frakcije otpadnog ambalažnog stakla, vrijeme postizanja maksimalne specifične provodnosti se odgađa.
Abstract (english)	The paper analyzes the effect of the addition of various fraction of waste container glass on normal consistency of cement pastes. Tests were carried out on portland cement paste with addition of 20 wt. % of waste glass with different fractions (<45 μm, 125-250 μm and 250-500 μm) at 20 °C i 1007 hPa. By introducing waste container glass into the cement-water system, the reaction system is expanding and becoming more complex. New interactions are occurring in the system, and as a result new equilibrium and equilibrium systems are established. 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 normal consistency of cement paste depends not only on the chemical part of the cement but also on the specific surface of the cement pores, fine milling of the waste container glass, water factor and temperature. With the addition of waste container glass, the value of electrical conductivity decreases except for the finest fraction. With the addition of fine and medium fine fractions of waste container glass it takes more time to achieve maximum specific electrical conductivity.
