“…This type of fiber reinforced concrete is often used in construction applications where the concrete will be subject to high stress or impact. PPT-PFRC has been built to strengthen such properties (Chaduvula et al, 2014). Fibers are engineered to increase tensile, flexural, durability, and impact strength, as well as adjust failure mode by enhancing post-cracking ductility and crack control.…”

“…The comparative analysis of plain concrete and PPT-PFRC has three outputs, such as axial force, shear force, and bending moment. Strength, toughness, and split resistance are the major tasks of PP fiber in concrete (Chaduvula et al, 2014). PP fiber permits tunnel lining to generate lesser deformations and strains to resist surrounding rock deformations, making it more suited for use in big deformation sections of tunnel lining in the soft surrounding rock.…”

Polypropylene (PP) fibers have properties suitable for reinforcement in concrete. Polypropylene Triangular Polyester Fiber Reinforced Concrete (PPT-PFRC) is a type of fiber reinforced concrete that uses a combination of PP and triangular polyester fibers to enhance the strength and durability of the concrete. The study analyses the properties of hardened concrete and PPT-PFRC mixes to study the axial force, shear force, and bending moment between normal and PPT-PFRC specimens. The researchers are currently attempting to analyze tunnel lining behavior in a static state, although FRC offers more advantages in seismic vibration and blast loading. The goal of this study is to investigate utilization of PPT-PFRC in a tube tunnel to improve the strength of the tunnel. The comparison shows that ordinary concrete has two significant flaws, i.e., poor strength and low strain, however, PPT-PFRC concrete has more toughness and vibration damping.

“…In these areas, -20°C temperature is common in winter season but during summer temperature may vary up to 35°C. This seasonal variation is responsible for the multiple changes in soil properties present there (Chaduvula, Desai & Solanki, 2014). The changes may be the occurrence of strength reduction, swell increase, loss in permeability, dynamic properties etc.…”

Across the globe, cold region areas experience frequent freeze and thaw cycles. Sometimes these natural cycles become so impacteous that the engineering properties of soil get affected adversely and supported structures like pavements damage or collapse by the time. In the present study chicken eggshell powder, sodium chloride and polypropylene fibres were used to stabilise the soil. Strength properties of 21-day cured virgin and treated soil samples were determined after keeping under 3, 5 and 10 freeze-thaw cycles. For durability assessment, mass loss was also determined after the same number of freeze-thaw cycles. Finally, optimal conditions were determined through analysis of variance. Results showed that the natural additives and synthetic fibres promise as better provision against harsh weather conditions. Design of experiments was made by the Taguchi technique using a statistical software Minitab® 17. Further analysis was done to find out the probability distribution of the responses. Probability distribution showed a large variation in the responses that implies that although the results were found satisfactorily as per the engineering purposes, yet not suitable to make any relationship between strength and durability properties.

“…On the other hand, fiber has been widely used in clay reinforcement due to its high strength, desirable frost and acid resistance, and reasonable water absorption and dispersion characteristics [27][28][29][30][31]. Previous studies show that the addition of fiber, such as polypropylene fiber (PPF), can effectively reduce the generation and diffusion of cracks in lime-stabilized clay [32], lime mortar [33], fly-ash-based geopolymer composites [34], cement-stabilized clay [35][36][37], which is an effective method for improving the frost resistance. However, the optimal amount of fiber in the coastal cement clay, as well as the improvement range of strength and the modification effect of ductility in different environments, needs further systematic research.…”

This study aimed to investigate the feasibility of using polypropylene fiber-cement-stabilized coastal clay as base-course material or foundation material for city sustainable development by assessing its mechanical performance. The influence of the number of freeze–thaw cycles and curing ages on the mechanical properties of ordinary cemented clay (OCC) and polypropylene fiber-cemented clay (PCC) was investigated by using unconfined compressive test. The experimental results show that the addition of fiber with 1% content can increase the strength as well as the ductility of cemented clay by 12.5% and 15.6%, respectively. The strength of PCC and OCC at 22d age was 1.5 times than at 7d age. Under differently timed freeze–thaw cycles, the mechanical performance of PCC is improved, and, better than that, OCC improves by 11.8% in strength, 16.5% in strain and by 5% in degree of damage, indicating that fiber can improve the freeze–thaw resistance of cemented clay. The frost resistance of PCC and OCC increases with the increase in curing age. Finally, the variation of strength of OCC was explained through the change of micro-structure while the strength enhancing mechanism of polypropylene fiber for cemented clay was also revealed.
