Bond stress-slip relationship of oil palm shell lightweight concrete

Bond stress-slip relationship of oil palm shell lightweight concrete

This paper presents the investigation on the local bond stress-slip behaviour of lightweight oil palm shell concrete (OPSC). The bond properties of the OPSC specimen with varying reinforcing bar diameters (12 and 16 mm), concrete cover sizes (50, 75 and 100 mm) and compressive strengths (25 and 35 M...
