For this study, the mixes were divided into two parts. First with glass powder as a binder in a replacement proportion of 10%, 20% and 30% in mass of cement corresponding to 45g, 90g, and 135g, respectively. Second, the same amount in the mass of powder was used as fine aggregate, corresponding to 3.3% (45g), 6.6% (90g) and 135% (135g). The potential alkali-silica reactivity was verified using the ASTM accelerated mortar-bar method C1567. The length measurements were taken following the ASTM C490. As a result, the replacements of binder using BIN 20%, BIN 30% and aggregate using AGG 10% showed no deleterious expansion using a method the ASTM AMBM C1567.
