Title: DETERIORATION OF CONCRETE CHIMNEYS
Accession Number: 00213698
Record Type: Component
Abstract: SAMPLES FROM TWO DAMAGED CONCRETE FACTORY CHIMNEYS WERE EXAMINED. THE CHIMNEYS HAS BEEN EXPOSED TO SEVERELY AGGRESSIVE CONDITIONS. DURING THE FIELD EXAMINATIONS, CRACKS IN THE CONCRETE WERE OBSERVED IN BOTH CASES. AT SOME PLACES THE CRACKING WAS SO SERIOUS THAT PIECES OF CONCRETE WERE LOOSE. CONCRETE SAMPLES FROM THE CHIMNEYS WERE EXAMINED BY X-RAY DIFFRACTION ANALYSES, CHEMICAL ANALYSES, AND BY THIN SECTION OBSERVATIONS. THE CONCRETE FROM BOTH CHIMNEYS WAS CARBONATED AND IN BOTH SAMPLES SULFATE REACTIONS HAD OCCURED. FURTHERMORE, ALKALI-AGGREGATE REACTIONS HAD OCCURED IN THE CONCRETE FROM ONE OF THE CHIMNEYS. /AUTHOR/
