The infrastructure boom has driven up cement demand to 30 billion tons annually. To address this and promote sustainable construction, researchers are developing solutions for carbon-neutral building practices, aiming to transform industrial waste into an eco-friendly alternative. This study aims to develop and enhance the mechanical and durability properties of alkali-activated composites (AACs) by incorporating varying amounts (5, 10, 15, and 20%) of finely ground bagasse ash (GBA) and polyvinyl alcohol (PVA) fibers.

- Concrete structures often crack, leading to issues with their integrity and durability, and traditional repair methods using ordinary Portland cement can cause further shrinkage cracks.
- Alkali-activated binders (AAP) show potential as a better repair material, especially when combined with varying amounts of polyethylene (PE) fibers; AAP with 1.25% PE fibers demonstrated the best tensile and flexural strength.
- Testing showed that AAPs significantly improve the compressive strength of repaired concrete, reducing initial strength loss and indicating that they could be a more effective and sustainable solution for concrete repair.
