Structural Performance of Energy Efficient Geopolymer Concrete Confined Masonry: An Approach towards Decarbonization

Geopolymer concrete is preferred over OPC due to its use of energy waste such as fly ash, making it more sustainable and energy-efficient. However, limited research has been done on seismic characterization in confined masonry, highlighting a gap earthquake-resistant structures. Our study compares the performance alkali-activated fly-ash-based geopolymer bare frame masonry wall panels with conventional concrete. Experimental results showed that 3.5% higher initial stiffness 1.0% lateral load-bearing capacity compared exhibited 45.2% 4.1% ultimate than traditional The experimental were verified using numerical simulation technique ANSYS-APDL, showing good correlation. Comparison previously tested walls revealed GPC similar structural behavior cement masonry. This demonstrates made from ash low-energy substitute for concrete, particularly highly seismic-prone areas, cleaner environment.
