摘要：

This paper presents an investigation into durability of alkali-activated slag (AAS) concrete exposed to alkali-aggregate reaction (AAR). In the concrete prism test method (ASTM C 1293), reactive aggregates introduced in the AAS matrix reacted with alkali-silica nel formed around aggregates. The expansion of PLAS concrete prisms was 0.04% after 50 days and 0.1% after 22 months. The expansion in OPC concrete was about 0.03% after 22 months of experiment. It was found that AAS concrete had lower resistance to alkali-aggregate attack than that of OPC concrete of similar grade. (C) 2001 Elsevier Science Ltd. All rights reserved.
