Abstract
Utilizing recycled coarse aggregate derived from concrete demolition waste is a strategy to reduce the exploitation of natural aggregates while supporting sustainable construction practices. However, the use of recycled aggregate generally tends to compromise the mechanical properties of concrete, necessitating the use of supplementary materials to restore its performance. This study aims to evaluate the effect of adding polypropylene fibers (SikaFiber PPM-12) on the mechanical characteristics of concrete incorporating recycled coarse aggregate from demolition waste as a substitute material. Concrete mix design was conducted in accordance with SNI 7656:2012, targeting a design compressive strength of 25 MPa. SikaFiber PPM-12 dosages were set at 0.5 kg/m³ and 0.7 kg/m³, combined with the superplasticizer Sika ViscoCrete-3115 N. All specimens underwent a 28-day water-curing process before being tested for compressive strength, splitting tensile strength, flexural strength, and alkali-silica reactivity potential (using the ASTM C1260 method). The results indicate that using 30% recycled coarse aggregate without additives led to a reduction in mechanical properties compared to conventional concrete. The addition of SikaFiber PPM-12 combined with Sika ViscoCrete-3115 N improved both workability and mechanical properties. These improvements were evident at a fiber dosage of 0.5 kg/m³ and were further optimized at 0.7 kg/m³, yielding higher compressive, splitting tensile, and flexural strengths compared to the fiber-free mix. These findings demonstrate that the combination of polypropylene fibers and superplasticizer is effective in mitigating the performance loss associated with recycled aggregate usage.
