Abstract
Thirty-five batches of concrete made from 17 different aggregates made from 5 different clays were investigated. Aggregates were tested for chemical, physical, and mechanical durability by a variety of tests. Relations between clay raw material, aggregate and processing parameters were determined. Concretes were tested for strength, chemical and physical durability. Results indicate that (a) nonbloated synthetic aggregate is potentially useful in Portland cement concrete base, (b) drying of concrete greatly improves its freeze-thaw durability, (c) aggregate quality varies significantly with processing parameters, and (d) improvements in aggregate quality control test procedures are required.
