【 摘 要 】

The amount of municipal waste produced is increasing every year. Waste preventing is the best way, but it is not always possible. There is a need to look for new ways of municipal waste management, such as material recovery of waste in the construction industry. This paper shows the possibilities of using glass waste in the production of concrete. Three fractions of glass bottle cullet - 0/4, 4/8 and 8/16mm, as a full-scale replacement of natural aggregates were used. The results of the compressive strengths of more than 50 MPa and the bending compressive strength at more than 4.4 MPa, show considerable potential in this direction of use. In addition, at half of the prepared samples, cement was replaced by fly ash from biomass combustion. The negative effect of alkali-silica reaction of glass did not appear in our experiment.
