ALKALI-SILICA REACTION OF CONCRETE CONTAINING GLASS - INTERACTION WITH REACTIVE AGGREGATES

摘要

In many areas, quantities of recovered glass remain after recycling, for which alternative uses must be found. One possible alternative outlet is the use of glass in concrete. The main concern is that glass is capable of undergoing alkali-silica reaction (ASR). However, the material also contains significant quantities of sodium. If released, this sodium may contribute to further reaction of glass and / or other reactive aggregates. This paper reports on the two-year results of one part of a larger testing programme which examined the expansion of concrete containing combinations of powdered glass and three UK-sourced aggregate combinations known to undergo ASR.
