TESTING FOR DELETERIOUS MATERIALS IN CONCRETE AGGREGATES

THE HARMFUL EFFECTS OF DELETERIOUS SUBSTANCES IN AGGREGATES WERE TESTED BY MEANS OF CONCRETE BEAMS IN WHICH THE COARSE AGGREGATES WAS COMPOSED ENTIRELY OF PARTICLES OF THE MATERIALS UNDER SUSPICION. THE BEAMS WERE TESTED IN FLEXURE AND SUBJECTED TO FREEZING AND THAWING. BREAKAGE UNDER FREEZING AND THAWING AND LOW STRUCTURAL STRENGTH INDICATED THE MATERIALS WHICH HAD BAD EFFECTS. THIS APPEARS TO B A BETTER METHOD OF TESTING THAN FREEZING AND THAWING OF THE AGGREGATES ALONE. /AUTHOR/
