“…This means that the flexural strength increased by 122, 168, 254, 286, 304, and 327% respectively compared with the unreinforced geopolymerized sand. These observations are in line with the results reported by (Sakthivel et al, 2019;Sukontasukkul & Jamsawang, 2012).…”

“…Remarkable ductility and good impact resistance characterizing PE along with light weight and high tensile strength of PP make polyolefins particularly suitable for manufacturing consumer goods, including food packaging, pipes, and covers, as well as automotive and aerospace elements. Several studies have been conducted on FRCCs and FRCs reinforced with recycled polyolefin fibers, assessing their good performance reached at an almost negligible cost [23][24][25]. Among them, a recent contribution by Signorini et al [26] investigated the mechanical and environmental performance of fully-recycled blended PE/PP filaments, obtained from disposed artificial turf pitches for sport facilities.…”

The use of virgin and recycled plastic macro fibers as reinforcing elements in construction materials has recently gained increasing attention from researchers. Specifically, recycled fibers have become more attractive owing to their large-scale availability, negligible cost, and low environmental footprint. In this work, we investigate the benefits related to the use of fully-recycled synthetic fibers as dispersed reinforcement in Fiber Reinforced Cement Composites (FRCCs). In light of the reference performance of FRCCs including virgin polypropylene (PP) fibers only, the mechanical response of composites reinforced with polyolefin filaments treated with a sol-gel silica coating and polyethylene terephthalate (PET)/polyethylene (PE) cylindrical draw-wire fibers is here assessed through three-point bending tests. Remarkably, recycled polyolefins lead to a notable enhancement in terms of peak strength and post-crack energy dissipation capability. This improvement is ascribed to both the flattened shape of fibers and the surface coating, which turns out to be very effective at strengthening the fiber-to-matrix bond. On the other hand, PET/PE fibrous reinforcement generally leads to a lower toughness, if compared to the virgin fibers. However, no reduction in terms of peak stress is evidenced. Balancing the significance of mechanical performance and environmental sustainability in the framework of a circular economy approach, both fully-recycled fibers at hand can be regarded as promising candidates for innovative structural applications.

The present investigation is on strength characteristic of hardened concrete with materials re-placement of fine aggregates and addition of fibre by using self-compacting concrete method which is an advanced technology used in improving the construction methodology. The SCC requires an admixture like Poly Carboxylate Ether (PCE) based super – plasticizer (Master Glenium SKY 8630) used as curing compound to improve the efficiency of self-compacting concrete SCC in terms of its performance. As the nominal fine aggregate cost is increasing the re-placement of fine aggregates is done by by-products of steel industry and query dust. Grade of concrete, dosage of admixtures, self-curing compounds, and time of curing are parameters to be considered for investigation. The performance studies include water retention, compressive test and split tensile test. The result analysis shows that crusher dust and foundry sand show increase in tensile and flexural strength at 0.2% of fibre addition. The grade of concrete is M30 is taken for investigation.
