Q. Does the selection of aggregates affect concrete durability? A. Yes. Selecting aggregates that are stable and durable by themselves has always been a primary requirement for durable concrete. Recent developments, however, have shown that sometimes aggregates that are durable by themselves can be deleteriously reactive with alkalies from the cement or elsewhere.
