Interface Shear of Fly ash and GGBS Based Geopolymer Concrete
Keywords:Interfacial shear, Fly ash. GGBS, ACI 318, Shear Friction, Geopolymer concrete
This article presents an experimental study conducted to find the shear strength of geopolymer concrete. In addition, it was proposed to check the suitability existing equations like Birkeland and Birkeland, Mattock and Design code ACI 318, which are developed for ordinary Portland cement concrete for estimating the shear capacity of geopolymer concrete. Push off Samples were used to study the shear strength at the interface. Both reinforced concrete and non-reinforced concrete samples were used for investigation. It was observed that the shear strength of geopolymer concrete is superior to OPC concrete. The existence of reinforcement transversely shear plane produced a rise of about 29% of the shear resistance against slip.
