EFFECTS OF REVIBRATION ON THE PROPERTIES OF CEMENT CONCRETE

STUDIES WERE MADE AND TESTS CONDUCTED TO DETERMINE EFFECTS ON THE PROPERTIES OF CEMENT CONCRETE BY REVIBRATION AT REGULAR INTERVALS UP TO FOUR HOURS AFTER PLACING. LABORATORY TESTING OF 6 IN. X 6 IN. X 24 IN. BEAM SPECIMENS CAST WITH CONCRETE OF DIFFERENT WATER-CEMENT RATIOS BUT WITH SAME MIX WAS DONE. THE SPECIMENS WERE TESTED FOR COMPRESSIVE STRENGTH, FLEXURAL STRENGTH AND WATER ABSORPTION. NON- DESTRUCTIVE TESTING WITH ULTRASONIC APPARATUS AND IMPACT HAMMER WAS ALSO DONE. FIELD TESTS WERE CONDUCTED ON TEN AND ONE-HALF FEET LONG RECTANGULAR CONCRETE BEAMS BOTH PLAIN AND REINFORCED HAVING DIFFERENT WATER-CEMENT RATIOS BUT THE SAME MIX. IT WAS CONCLUDED THAT BY REVIBRATION BOTH COMPRESSIVE AND FLEXURAL STRENGTHS WERE IMPROVED AND WATER ABSORPTION WAS REDUCED. /AUTHOR/
