WEATHERING OF SERPENTINE AGGREGATES

THIS REPORT DEALS WITH THE RAPID WEATHERING OF SERPENTINE AGGREGATES IN AN AUTOCLAVE-TYPE DEVICE. SAMPLES OF SERPENTINE AGGREGATE FROM THREE SOURCES WERE SUBJECTED TO 10 WEATHERING CYCLES EACH AND THE RESULTS WERE COMPARED WITH THE RESISTANCE TO RAPID WEATHERING OF A STANDARD AGGREGATE. IT WAS CONCLUDED THAT SERPENTINE AGGREGATES ARE NOT HIGHLY SUSCEPTIBLE TO CHEMICAL WEATHERING. AT THIS TIME WE HAVE NO REASON TO EXPECT A POOR PERFORMANCE FROM SERPENTINE AGGREGATES THAT PASS ALL OF THE REQUIRED PHYSICAL TESTS. /BPR/
