EXPERIMENTAL CONCRETE PAVEMENT CONTAINING FLY-ASH ADMIXTURES

RECORDS OF CONSTRUCTION AND PERFORMANCE OF A PORTLAND CEMENT CONCRETE PAVEMENT CONTAINING FLY-ASH AS AN ADMIXTURE ARE PRESENTED. FOUR TO FIVE AIR-CONTENT AND SLUMP TESTS WERE PERFORMED DAILY DURING THE COURSE OF THE PROJECT. CEMENT UTILIZED HAD A SPECIFIC GRAVITY OF 3.15 AND A BLAINE FINENESS OF 3,352 SQ. CENT. PER GRAM. THE FINE AGGREGATE WAS DREDGED RIVER SAND AND WAS SOMEWHAT DEFICIENT IN FINES. THE MINIMUM EXPECTED 28-DAY STRENGTH OF PORTLAND CEMENT CONCRETE AS REQUIRED BY THE DEPARTMENT IS 3,500 POUNDS PER SQUARE INCH IN COMPRESSION AND 600 POUNDS PER SQUARE INCH MODULUS OF RUPTURE. SPECIMENS CAST FROM MIXTURES PLACED IN ALL SECTIONS EXCEEDED THE REQUIRED STRENGTHS BY A SUBSTANTIAL AMOUNT. CONSIDERING THE PERFORMANCE OF THE PAVEMENT SECTIONS AND THE RESULTS FROM DURABILITY AND STRENGTH TEST, IT IS RECOMMENDED THAT THE DEPARTMENT TAKE NECESSARY ACTION TO ENABLE THE FURTHER USE OF FLY-ASH IN PAVEMENT CONCRETE AND IN BRIDGES.
