CEMENT PERFORMANCE IN CONCRETE

TESTS WERE CONDUCTED ON 22 PORTLAND CEMENTS TO DEVELOP PERFORMANCE DATA ON THE DIFFERENT TYPES OF CEMENT AND, WHEN POSSIBLE, TO COMPARE THE DATA DEVELOPED WITH THOSE OBTAINED BY THE PORTLAND CEMENT ASSOCIATION (PCA). A SAMPLE OF EACH CEMENT WAS SIEVED TO DETERMINE THE PERCENTAGE OF LUMPS FORMED DURING 10 YEARS STORAGE, AND WAS THEN SUBJECTED TO CHEMICAL ANALYSIS, PHYSICAL TESTS, AND HEAT OF HYDRATION TESTS. AIR-ENTRAINED CONCRETE MIXTURES WERE PROPORTIONED WITH EACH CEMENT. SPECIMENS WERE MADE FOR A TEST IN THE FRESHLY MIXED AND HARDENED CONDITION. THE EFFECTS OF 10-YEAR STORAGE WERE FOUND TO BE NEGLIGIBLE. IN GENERAL, TEST RESULTS COMPARED WELL WITH THOSE OF PCA. ANALYSIS OF DATA ON SULFATE RESISTANCE AND CRACKING RESISTANCE WERE MADE. IT WAS INDICATED THAT RESULTS OF THESE TWO TESTS ARE INFLUENCED NOT BY THE CHARACTERISTICS OF THE CEMENT THAT MIGHT BE EXPECTED TO AFFECT SUCH PERFORMANCE, BUT ALSO BY THE RATE OF REACTION OF THE CEMENT WITH WATER TO DEVELOP HYDRATION PRODUCTS AND BY STRENGTH AND RELATED ATTRIBUTES. /AUTHOR/
