FLEXURAL PROPERTIES OF REINFORCED RECYCLED CONCRETE BEAMS

摘要

Flexural properties of reinforced recycled concrete (RRC) beams are investigated experimentally. Their parameters are water-cement ratio, type, combination of aggregates and usage of expansive additive. Flexural properties of RRC beams, i.e. cracking moment, maximum crack spacing, maximum crack width, deflection under serviceable load and plastic deflection are discussed. Experimental results indicate the mechanics-based possibility of utilizing recycled concrete for reinforced concrete structures under the proper design as well as within the proper limit of application.
