Polypropylene fiber reinforcement is an effective method to enhance the durability of concrete structures. With increasing public interest in widespread use polypropylene reinforced (PFRC), necessity evaluating mechanism (PF) on permeability has become prominent. This paper describes influence PF exposed freeze-thaw cycles under compressive and tensile stress. The PFRC loads accurately measured by a specialized setup. loads, volume change load, relationship between stress levels at minimum points are discussed. results indicate that addition adversely affects without damage cracks. However, it decreases specimens cracking. Under initially slowly follows significant increase as level increases. phenomenon correlates with specimen. point exhibit linear correlation, fitted proportional function parameter γ ≈ 0.98872. increases gradually radial deformation increase. strain-permeability curves loading studied consist two stages. In stage I, strain while load. II, cycles, whereas cycles. reduction load greater than future research, can be integrated its constitutive provide reference for application waterproofing

This study evaluated the potential and environmental benefits of using oil shale residue as a replacement for fine aggregate in concrete through series experiments. Initially, crushing value test confirmed residue’s at 16.7%, meeting load-bearing standards aggregates, thus proving its viability complete substitute. Further, was treated with 60 mg/L concentration Tween 80 other surfactants removal. The specimens demonstrated excellent compressive performance dense internal structure. Building on this, mechanical properties were explored across different ratios (from 40% to 100%), revealing an increase strength higher ratios. In durability tests, compared JZ group, modified desulfurization gypsum exhibited 0.03% reduction mass loss rate 10.13% relative moving elasticity modulus rate, particularly noticeable after 175 freeze–thaw cycles where B1 B4 no significant damage, highlighting remarkable durability. Overall analysis indicated that oil-removed substitute concrete, combined modification, not only enhances but also significantly reduces consumption natural aggregates pollution, promoting resource utilization sustainable development.
