Resumen

This study evaluates the impact of crushed scallop shell waste (CSS) and recycled cellulose fibres (CF) in pervious concrete, analysing their influence on workability, permeability, and mechanical properties. Rheology, permeability, and mechanical strength tests were conducted on cementitious matrices and pervious concrete with different proportions of CSS and CF. The results show that CSS improves compaction and early strength by acting as an inert filler, while CF enhances ductility and controls crack propagation. Combining 10 % CSS with 1.35 kg/m³ CF optimises the balance between permeability and strength. The results indicate that the optimised mixture achieved a permeability of 18.9 mm/s and compressive, flexural, and tensile strengths of 10.2 MPa, 2.82 MPa, and 1.54 MPa, respectively. The findings highlight the potential of these recycled materials in sustainable concrete design.
