Abstract: The paper presents tests performed on a metakaolin-based geopolymer containing crushed cathode-ray tube (CRT) glass waste in a form of an aggregate. CRT glass constitutes a problematic type of waste which is hard to recycle. The paper describes the possibility of CRT glass application in the geopolymer matrix. During the research, six mixtures containing different metakaolin to CRT glass ratio were subjected to flexural and compressive strength tests. Samples containing glass waste showed very good strength results. Samples prepared with the use of a mixture containing 50% of crushed glass exhibited the highest average flexural strength (6,6 MPa) and the highest compressive strength (51,0 MPa). One mixture was deemed the most promising, and as such was subjected to further testing which showed that the increase of NaOH concentration leads to an increase in mechanical strength.
