“…In the past research works, the effect of fibre inclusion on compressive strength is inconclusive as there were contrasting observations made; there were researchers who reported improvement in the compressive strength with certain dosage of fibre addition whereas on the other hand there were findings of lowering compressive strength with fibre addition [22][23][24][25]. Table 3 shows that the effect of fibre on the compressive strength of the FRCC mixes was minimal as the percentage difference was only ±12%.…”

Fibre-reinforced cementitious composite (FRCC) is a type of composite that uses high volume of fibres to attain ductile properties. In this research, the effects of two different fibres, namely polyvinyl alcohol (PVA) and basalt, on the mechanical properties of FRCC such as compressive, splitting tensile and flexural strengths were investigated. The fibres were used in varying volume fraction, which includes 1.0%, 1.5% and 2.0% and a hybrid combination of 1.5% basalt fibre with 1.5% PVA fibre for the preparation of the FRCC. The results showed that while the fibres had minimal effect on the compressive strength of FRCC, significant improvements in the splitting tensile and flexural strengths were found. In the comparison of the flexural performances, the introduction of PVA fibre in FRCC led to superior properties and it exhibited more ductile failure mode compared with basalt fibre and the optimum fibre dosage to be added was determined to be 1.5%.

“…The obtained results indicate that the concrete specimens reinforced with 1% WPFT fibres performed better in enhancing the impact resistance and energy absorption of concrete. Besides, Mastali et al [33] and Fakharifar et al [43] reported a linear correlation between the impact resistance and fibre content for concrete containing glass fibres and polypropylene fibres with R 2 higher than 0.96.…”

Towards Sustainable Concrete Composites through Waste Valorisation of Plastic Food Trays as Low-Cost Fibrous Materials

Recycling of waste plastics is an essential phase towards cleaner production and circular economy. Plastics in different forms, which are non-biodegradable polymers, have become an indispensable ingredient of human life. The rapid growth of the world population has led to increased demand for commodity plastics such as food packaging. Therefore, to avert environment pollution with plastic wastes, sufficient management to recycle this waste is vital. In this study, experimental investigations and statistical analysis were conducted to assess the feasibility of polypropylene type of waste plastic food tray (WPFT) as fibrous materials on the mechanical and impact resistance of concrete composites. The WPFT fibres with a length of 20 mm were used at dosages of 0–1% in two groups of concrete with 100% ordinary Portland cement (OPC) and 30% palm oil fuel ash (POFA) as partial cement replacement. The results revealed that WPFT fibres had an adverse effect on the workability and compressive strength of concrete mixes. Despite a slight reduction in compressive strength of concrete mixtures, tensile and flexural strengths significantly enhanced up to 25% with the addition of WPFT fibres. The impact resistance and energy absorption values of concrete specimens reinforced with 1% WPFT fibres were found to be about 7.5 times higher than those of plain concrete mix. The utilisation of waste plastic food trays in the production of concrete makes it low-cost and aids in decreasing waste discarding harms. The development of new construction materials using WPFT is significant to the environment and construction industry.

“…Fakharifar et al [10] statistically evaluated the effect of fiber content on compressive and flexural strengths through adequate tests and found that the first crack and failure strength as well as mechanical properties were enhanced by increasing the fiber content. Ma et al [11] suggested that excessive amounts of fly ash tend to decrease the compressive strength though ductility improved with fly ash content.…”

It has been widely recognized that the constitutive model plays an essential role in engineering application of high ductile fiberreinforced concrete (HDC). In this research, uniaxial compressive tests were conducted on nine groups of HDC specimens with different mixture ratios and one group of mortar matrix specimens as comparison, discussing the effect of fiber content, watercement ratio, fly ash content, and sand-binder ratio. According to the characteristics of stress-strain curve of HDC under uniaxial compression, a damage constitutive model was proposed by introducing two damage threshold parameters and then was compared with other existing models. Results indicated that the damage model curves suggested in this paper were best consistent with experimental curves and substantially demonstrate the damage evolution process as well as the cracking resistance effect of fiber bridging stress.
