Comparative analysis of ASTM C1202 and SRPS EN 12390-18 testing methods for assessing chloride ion penetration in concrete supplemented with recycled CRT glass as cementitious material

<p>Durability is crucial for reinforced concrete, directly influencing the service life of structures. The presence of aggressive agents, especially chloride ions, significantly impacts durability. This study investigates the differences between ASTM C1202 and SRPS EN 12390-18 standards in concrete supplemented with recycled CRT glass as cementitious material. The percentage of replacement of cement with glass is: 10% and 20%, by mass. In addition to fresh state testing, the following mechanical tests were also performed: compressive strength and splitting tensile strength. The aim of this research was to determine how the addition of finely ground cathode glass affects the resistance of concrete to chloride penetration, as well as to compare the results of chloride penetration after conducting two standardized but completely different test procedures. A review of the literature revealed very few comparative tests of chloride penetration according to the mentioned standards.</p>
