EFFECTS OF ADDITION OF FINELY GROUND CRT GLASS ON THE RESISTANCE OF CONCRETE TO CHLORIDE ION PENETRATION

Durability is a critical aspect of reinforced concrete, as it directly affects the service life of structures. The presence of aggressive agents, particularly chloride ions, significantly impacts durability. This study evaluates the resistance to chloride ion penetration in concrete with addition of recycled cathode ray tube glass as a SCMs (supplementary cementitious material). Cement was replaced with cathode ray tube (CRT) glass at two levels: 10% and 20% by mass. In addition to tests conducted on fresh concrete, mechanical properties such as compressive strength and splitting tensile strength were examined. The objective of this research was to assess the effects of addition of finely ground CRT glass on the resistance of concrete to chloride ion penetration, in accordance with the SRPS EN 12390-18 standard. The literature search revealed a lack of papers in which this test on concrete with glass addition was conducted according to the European standard.
