STEEL FIBERS AND LIGHTWEIGHT BEAMS

THE AUTHOR DISCUSSES THE USE OF STEEL FIBERS IN REINFORCED CONCRETE AS A MEANS OF REDUCING THE DEFLECTION OF LIGHTWEIGHT AGGREGATE LOAD BEARING MEMBERS, THIS DEFLECTION BEING GREATER THAN THAT OF MEMBERS OF NORMAL WEIGHT CONCRETE. LOAD-DEFLECTION CURVES ARE GIVEN FOR FOUR BEAMS WITH THE FOLLOWING AGGREGATES; (A) GRAVEL; (B) AGLITE LIGHTWEIGHT AGGREGATE: (C) AGLITE & 1.2% VOL. FIBERS; AND (D) AGLITE & 1.6% VOL. FIBERS. THE LOAD WHICH INDUCED CRACKING IN THE FIBER REINFORCED BEAM WAS APPROXIMATELY TWICE THAT WHICH INDUCED CRACKING IN THE PLAIN AGLITE BEAM. /TRRL/
