Abstract
The purpose of the present study was to use two solid wastes—fly ash and mixed color waste glass—as constituents in concrete materials. The fly ash with water glass as activation chemical was used as a binder in the concrete, and the waste glass particles were used as aggregate to replace nature aggregate. The present study focused on the potential of alkali-silica reaction (ASR) of glass aggregates used in portland cement mortar and in water-glass activated fly ash (WAFA) mortar. The ASR potential was examined using the accelerated testing method, ASTM C-1260. The results showed that with 10% substitution of natural aggregate by glass particles, the ASR expansion of portland cement mortar depends on the size of glass aggregate. The ASR expansion of WAFA mortar does not depend on the sizes of glass aggregate but on the content of glass aggregate. The ASR expansion of WAFA mortar was below the critical ASR expansion up to 100% of replacement by glass aggregate. The color of glass does not affect the ASR potential of WAFA mortar.
