Influence of Steel Fibers on the Interfacial Shear Strength of Ternary Blend Geopolymer Concrete Composite

Sustainable development is a major issue confronting society today. Cement, constituent of concrete, key component any infrastructure development. The drawback cement production that it involves the emission CO2, predominant greenhouse gas causing global warming. geopolymers has resulted in decrease production, as well reduction CO2 emissions. During mass concrete construction very large structures, interfaces/joints are formed, which potential failure sites crack formation. Concrete may interface with other different strengths, or materials, such steel. To ensure monolithic behavior composite bond strength at should be established. can ensured by usage shear ties across interface. However, an increase number reduce efficiency. present study aims to determine interfacial geopolymer substrate, and high-strength overlay, adding 0.50%, 0.75%, 1% crimped steel fibers, two three ties, push-off specimens. It was found replaced 0.75% fibers. In addition, method proposed predict composite, comparable test results.
