NONBLOATED SYNTHETIC AGGREGATE CONCRETE

THIRTY-FIVE BATCHES OF CONCRETE REPRESENTING 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, AGGREGATES AND PROCESSING PARAMETERS WERE DETERMINED. CONCRETES WERE TESTED FOR STRENGTH AND CHEMICAL AND PHYSICAL DURABILITY. RESULTS INDICATE THAT (1) NONBLOATED SYNTHETIC AGGREGATE IS POTENTIALLY USEFUL IN PORTLAND CEMENT CONCRETE BASES, (2) DRYING OF CONCRETE GREATLY IMPROVES ITS FREEZE-THAW DURABILITY, (3) AGGREGATE QUALITY VARIES SIGNIFICANTLY WITH PROCESSING PARAMETERS, AND (4) IMPROVEMENTS IN AGGREGATES QUALITY CONTROL TEST PROCEDURES ARE REQUIRED. /AUTHOR/
