A4.1 – Definition of possible mix designs: reference concrete and concretes with different percentages of recycled and virgin synthetic fibers (reference)
A4.2 – Casting of specimens for chemical, physical, and mechanical tests
A4.3 – Fresh concrete physical tests (consistency with Vebè test and slump test)
A4.4 – Mechanical tests at 7 and 28 days (compression strength, tensile strength, three-point bending test with CMOD control, and determination of residual strengths and fracture energy)
A4.5 – Physical tests on hardened fiber-reinforced concrete (density, shrinkage, total water absorption, capillary absorption)
A4.6 – Morphological and compositional characterization of concretes containing composite waste fibers using SEM microscopy
