FLEXURAL BEHAVIOR OF PLAIN AND REINFORCED LIGHTWEIGHT AGGREGATE CONCRETE BEAMS UP TO 600 DEGREES CENTIGRADE

FLEXURAL TESTS WERE CONDUCTED ON CONCRETE AND REINFORCED CONCRETE BEAMS (50 X 75 X 846 MM) MADE OF LIGHTWEIGHT AGGREGATE AND ORDINARY PORTLAND CEMENT AS PART OF A GENERAL INVESTIGATION OF THE PROPERTIES OF CONCRETE AT ELEVATED TEMPERATURES. THE BEAMS WERE TESTED AT STEADY STATES OF TEMPERATURE IN THE RANGE 20 TO 600 DEG C. THE PROPERTIES INVESTIGATED WERE LOSS OF WEIGHT, THERMAL MOVEMENTS, ULTIMATE STRENGTH, AND FLEXURAL RIGIDITY UNDER UNIFORM DISTRIBUTION OF TEMPERATURE WITHIN THE SPECIMENS. THE PERFORMANCE OF REINFORCED CONCRETE BEAMS SHOWS CONTINUOUS DETERIORATION OF FLEXURAL PROPERTIES AT ELEVATED TEMPERATURE. PLAIN CONCRETES, ON THE OTHER HAND, LOSE IN STRENGTH AND RIGIDITY AT TEMPERATURES BELOW 100 DEG C AND GAIN STRENGTH AT HIGHER TEMPERATURE.
