FLEXURAL BEHAVIOUR OF REINFORCED CONCRETE BEAMS MADE WITH FLY ASH COARSE AGGREGATE

Tests are reported on the flexural behaviour of reinforced concrete t beams made with fly ash coarse aggregates and sand. Data on deflection, rotation, cracking, concrete and steel strains, design service and ultimate loads are presented. The results show that fly ash aggregate concrete beams can satisfy the serviceability requirements of deflection and cracking, and that they possess adequate ductility and load factor against flexural failure. It was found that a better estimation of short term deflection can be obtained if the contribution of the concrete in tension is neglected. Some of the beams may not fully satisfy long-term deflection requirements and this aspect should be considered in design. It is shown that fly ash aggregate concrete beams can give satisfactory structural performance according to British and American codes. (TRRL)
