NONBLOATED BURNED CLAY AGGREGATE CONCRETE

THIRTY-FIVE BATCHES OF CONCRETE MADE FROM 17 DIFFERENT AGGREGATES PREPARED FROM 5 DIFFERENT CLAYS WERE EVALUATED 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 NONBLOATED BURNED-CLAY AGGREGATE IS POTENTIALLY USEFUL IN PORTLAND CEMENT CONCRETE BASE AND THAT DRYING OF CONCRETE GREATLY IMPROVES ITS FREEZE-THAW DURABILITY. AGGREGATE QUALITY VARIES SIGNIFICANTLY WITH PROCESSING PARAMETERS, AND IMPROVEMENTS IN AGGREGATE QUALITY CONTROL TEST PROCEDURES ARE REQUIRED. /AUTHOR/
