Randomized trial assesses mechanical properties of flexible polymer concrete with waste fillers, highlighting potential for sustainable construction.
Key Points
This research aims to assess the mechanical performance of basalt fiber-reinforced flexible polymer concrete using waste materials to promote sustainable construction.
Experimental evaluation of mechanical properties using compressive, splitting tensile, three-point bending, and impact tests.
Optimization of polyurethane–fly ash composites and three-component (polyurethane–fly ash–waste glass) concrete compositions.
Incorporation of up to 2.5% basalt fibers by weight to reinforce flexible polymer concrete.
Basalt fiber reinforcement led to increases of up to 69.2% in splitting tensile strength, 23.4% in flexural strength, and 30.6% in impact strength.
The flexural polymer concrete exhibited an elongation of 14.3% and an impact strength of 11.10 kJ/m2.
Optimal compositions indicate potential applications in nonstructural repair and energy-absorbing materials.
