A Study of the Degradation of Cement Matrices Containing 2,4,5-Trichlorophenol

THE EFFECTS OF INDUSTRIAL HAZARDOUS WASTE OF 2,4,5-TRICHLOROPHEOL SOLIDIFED IN CEMENT ON WATER RESISTANCE AND PHYSICAL PROPERTIES SUCH AS BULK AND PYCNOMETRIC DENSITY, PORE VOLUME AND PORE DISTRIBUTION HAVE BEEN INVESTIGATED BY MERCURY INTRUSION POROSIMETRY. VARIABLE AMOUNTS OF 2,4,5-TCP AT A MAXIMUM CONCENTRATION OF 16.5 WT%, DECREASE THE COMPRESSIVE STRENGTH, DENSITY AND PORE VOLUME VALUES AS MEASURED ON NEAT CEMENT SAMPLES PREPARED WITH THE SAME WATER-TO-CEMENT RATIO W/C=0.55. THE ANALYTICAL PROCEDURE IS DESCRIBED. IT EMPLOYS SUPERLCO SPE LC-18 CARTRIDGES IN EXTRACTION OF 2,4,5-TCP FROM ACQUEOUS LEACHATE SAMPLES. COMPARED TO THE PREVIOUS RESULTS ON 1,3,5-TRICHLOROBENZENE, THE LEACHING EXPERIMENTS INDICATE A` VERY WEAK RETENTION OF 2,4,5- TRICHLOROPHENOL IMMOBILISED IN CEMENT.
