Abstract: With rapid advances in the electronic industry, the management of cathode ray tube (CRT) glass waste has become a major environmental problem. In this study, 25% Ordinary Portland cement was replaced by Fly ash (FA) or Ground granulated blast-furnace slag (GGBFS), the crushed CRT funnel glass sand untreated with nitric acid (n-TFG) was used to replace river sand fine aggregate of 0%, 25%, 50%, 75% in the mortar. The fresh, mechanical properties of the mortar were studied, the alkali-silica reaction (ASR) expansion, drying shrinkage and leaching of lead from mortar were evaluated. The test results showed, the use of n-TFG glass sand improves fresh properties of the mortar. The mortar with n-TFG glass sand has higher mechanical properties than control mortar. At the drying shrinkage period of 56 days, drying shrinkage of nearly all the mortar with n-TFG glass sand are higher than the limit of 0.075%. ASR expansion of the mortar are found to be below 0.1% at 14 days tested age, except the mortar with GGBFS and 75% n-TFG glass sand. The lead leaching from mortar with n-TFG glass sand was reduced comparing the content of the leachable lead from n-TFG glass sand. Moreover, at a given replacement level of n-TFG glass sand, FA series mortar has better fresh properties, a lower wet density, mechanical properties, drying shrinkage, ASR expansion and the leaching of lead than GGBFS series mortar.
