Title: Technique for Investigation of Internal Cracks in Reinforced Concrete Members
Author(s): Bengt B. Broms
Publication: Journal Proceedings
Appears on pages(s): 35-44
Keywords: beam, cracking, crack pattern, crack spacing, crack width, microscopic study, reinforced concrete, research, resin injection, technique
Abstract:A method is described by which the internal crack pattern, crack width, and crack spacing in reinforced members can be investigated. The method consists of injecting a resin into loaded tension or flexural reinforced concrete members. The applied load is maintained for 6 to 8 hr while the resin is allowed to set. The members are then cut open by a diamond saw and the internal cracks (maintained in their original positions) are studied with a microscope.
