Bond Strength Of Reinforced Laterized Concrete Beams.
(Premier Conference, 2006-08-17) Falade, F.; Oyekan, G.L.
This paper presents the results of an investigation into the effects of reinforcement diameter and embedment depth on the bond strength of reinforced laterized concrete beams. Four different bar diameters (12mm, 16mm, 20mm and 25mm) were considered. Three embedment depths were used; namely, 3d, 4d and 5d (d = bar diameter). The specimens were tested at curing ages of 7, 14, 21 and 28 days. The results show that (i) for a given depth, bond strength decreased with increase in reinforcement diameter (ii) the higher the depth, the higher the value of bond strength and (iii) generally there was increase in bond strength with age.
