“…In Ref. (11) , Abdulkareem M et al ( 2022) reviewed the durability of propylene fibre-reinforced concrete. The authors reported that the incorporation of polypropylene fibres at various rates into the concrete can limit the development of cracks by forming a bond bridge, modifying the pore network, and thus enhancing durability.…”

Objectives: To study the microstructural and durability properties of a polypropylene fibre reinforced concrete (PPFRC). Methods: In this research 10% and 15% of cement was replaced by natural zeolite and Alccofine and four different volume fractions of polypropylene fibre (0, 0.1, 0.2, 0.3 and 0.4 percent) were utilized to improve the strength and durability properties of concrete. Scanning Electron Microscope (SEM) was used to observe the crystal structure and that interfactial transition zone (ITZ). Findings: SEM Results indicates that fibres changes the microstructure, reduces Ca(OH 2 ) through the secondary C-S-H gel formation and hence the voids get reduced Six concrete mixtures with water to binder ratio of 0.50 were cast. Novelty: Addition of polypropylene fibre has greatly improved the durability properties of concrete containing alccofine and zeolite.

“…Among these, PPF concrete is a new type of composite material that improves toughness and fire resistance by adding fibers. It is less brittle than ordinary concrete and widely used in various civil and commercial buildings due to its simplicity of construction and affordability [1][2][3]. The frequent occurrence of fire incidents in recent years has caused significant harm to property and the safety of lives, and fires are recognized as major dangerous disasters.…”

This study aims to investigate the effect of high temperature on the mechanical properties of low-slump polypropylene fiber (PPF) concrete, and tests the tensile and compressive properties of 204 groups of low-slump PPF concrete with eight different dosages and four different lengths at normal temperature and after high temperature. The results of the compressive test showed that PPF can significantly improve the mechanical properties of concrete after high temperature when the fiber content is small, and the compressive strength of low collapse polypropylene fiber concrete after high temperature showed a tendency to rise and then fall at the same temperature with an increase of the fiber admixture. When the fiber content was 0.5 kg/m3, the compressive strengths of 3 mm, 9 mm, 15 mm and 19 mm reached their maxima, which were 9.65%, 11.33%, 7.90% and 2.87% higher than that of ordinary concrete, respectively. With an increase in fiber length, the effect of PPF on the compressive strength of concrete is not obvious. PPF at high admixture further increases the pore and air content in concrete, which decreases the compactness of the concrete, thus leading to a decrease in the compressive strength of the concrete. When the temperature was 800 °C and the fiber admixture was 5.0 kg/m3, the compressive strength of PPF concrete with different lengths reduced by 17.83%, 17.27%, 22.59% and 23.92%, respectively, compared to normal concrete. In addition, according to the results, the optimal combinations of strength at room temperature and after high temperature were 3 mm fiber length and 1.0 kg/m3 dosing and 9 mm fiber length and 0.5 kg/m3 dosing, respectively, which increased the compressive and tensile strengths by 17.15% and 25.72% at room temperature and by at least 6% and 20% after high temperature, compared to the concrete without fiber dosing. Moreover, the stress–strain constitutive equations of PPF concrete at normal temperature and after high temperature were established, which can be used for finite element simulation and related mechanical analysis of PPF after high temperature.
