LONG-TIME STUDY OF CEMENT PERFORMANCE IN CONCRETE--CHAPTER 11. REPORT ON THE CONDITION OF THREE TEST PAVEMENTS AFTER 15 YEARS OF SERVICE

TWENTY-SEVEN CEMENTS, DIFFERING WIDELY IN THEIR CHEMICAL AND PHYSICAL PROPERITES, WERE USED IN 3 PAVEMENTS EXPOSED TO DIFFERENT WEATHER CONDITIONS. AFTER 15 YEARS THE NEW YORK PAVEMENT EXHIBITS SURFACE SCALING ON ALMOST ALL SECTIONS CONTAINING THE NON-AIR-ENTRAINING CEMENTS. ALL SECTIONS CONTAINING AIR-ENTRAINING CEMENTS ARE STILL COMPLETELY FREE FROM SURFACE SCALE. ASIDE FROM SOME LIGHT SCALE OR SURFACE WEAR ON THE SOUTH CAROLINA PROJECT AND SOME D-CRACKING ON THE MISSOURI ROAD, ALL OF THE CEMENTS HAVE PERFORMED EQUALLY WELL ON BOTH PROJECTS. VARIATIONS IN THE CHEMICAL COMPOSITION AND FINENESS OF THE CEMENT APPEAR TO BE WITHOUT SIGNIFICANCE INSOFAR AS RESISTANCE TO FREEZING AND THAWING IS CONCERNED. /PCA/
