Effect of Synthetic Aggregate Thermal Transformation on Performance of Concrete
The investigation involved twelve different synthetic aggregates produced in the IIT rotary kiln, one commercially produced synthetic lightweight aggregate, and one regular weight aggregate. Each aggregate was used in concrete which was subjected to a variety of physical durability investigations including autoclave expansion, long-time reactivity, freeze-thaw, and shrinkage. From the results of the study, it was found that (a) incompletely burned synthetic aggregates resulted in poor performance in the standard ASTM C-29 freeze-thaw test for concrete, (b) destructive autoclave expansion occurred in some concretes and (c) neither long-time reactivity or shrinkage produced significant results.
