“…Due to the significant amount of recycled material, it is known as an environmentally beneficial material. They used the term "adobe and fibrous cement" for their invention, which was independently stated by Elaiwi et al (2020) [4]. The dead load of the main structure will be reduced as a result of this alternative building material called papercrete [5].…”

The environmental degradation in the vicinity of landfills or mills is caused by waste paper disposable. Each year, the industry's paper waste is increasing gradually. As a result, additional places are required for landfills, which consume energy, deplete natural resources, and increase expenditure and environmental pollution. Pollution can be reduced by adding WP to a concrete mixture in concrete production. This review paper investigates the physical and chemical properties of waste paper. Besides that, the mechanical properties of concrete containing waste paper, such as compressive, flexural, and splitting tensile strengths, are also studied in this review paper. All reviews of the intended studies include experimental tests. From the reviews, all strengths were increased with the inclusion of waste paper, either by addition, substitution, or replacement with fine aggregate, coarse aggregate, or cement. By using waste paper, not only would concrete have advantages and benefits, but also environmentally friendly construction materials could be produced from time to time. It has been noted in most studies that the inclusion of waste paper brings significant benefits. It can be concluded that waste paper potentially has favorable properties for concrete production. The concrete performance will improve in terms of compressive, flexural, and splitting tensile strengths with waste paper inclusion at certain percentages compared to ordinary concrete with no waste paper content.

“…Regarding the use of strengthening substances, a good deal of research demonstrates the relevance of including various fibres in gypsum mixtures [3,[18][19][20][21][22][23]. This is because the fibres increase the gypsum tensile strength and shape stability to support the mixture to reduce degradation and breakdown.Many researchers have studied the effect of even more substances such as steel fibre or chipped carbon fibres to reinforce a concrete mix, cement mortar, and asphalt concrete admixtures [24][25][26][27][28][29][30][31][32].The current work proposes to design Pure Gypsum (PG) of unique fibres that strengthen as a composite form by use of compact and ductile copper fibres haphazardly scattered in the gypsum. Copper fibres present high ductility [33] to improve problematic brittle material fractures to become ductile fractures and also block the tendency to pull-out from the gypsum.…”

This study investigates the efficacy, performance, and effect of chopped Copper Fibre (CF) on a Pure Gypsum (PG) mixture. The Copper Fibre (CF) is extracted from the waste of electrical wires that are considered as environmental waste. Three models of Copper Fibre (CF) with a diameter of 0.83 (mm) and lengths of 10 (mm), 20 (mm), and 30 (mm) (Aspect-Ratio L/d = 12, 24 and 36 respectively), with Volume Fraction (V.f.) for Copper Fibre (CF) by two Water/Gypsum Ratios (W/G) worth (0.5 and 0.6) are created. The mixtures are divided into two groups of W/G ratios. Each group contains four samples, one reference without Copper Fibre (CF) and the other three with the addition of Copper Fibre (CF) individually with different lengths. The results show that adding Copper Fibre (CF) to the Pure Gypsum (PG) mixture increases the Compressive Strength. Further, the effect is to heighten the Compressive Strength of Pure Gypsum (PG) when the Aspect-Ratio is raised. In other words, when the (W/G) Ratio is reduced, the Compressive Strength increases in the presence or absence of Copper Fibre (CF). Moreover, the efficiency of the Copper Fibre (CF) develops further when the W/G ratio is decreased.

“…The development of building materials over the last years leads to the development of synthetic fibers. Many fibers have been introduced and used successfully as nylon fibers [9], steel fibers [10,11], glass fibers [12], chopped carbon fibers [13] and polypropylene fibers [14][15][16][17][18]. The use of polypropylene fibers has many advantages since it is very effective in reducing the *Corresponding Author Institutional Email: israasaeed@uomustansiriyah.edu.iq (I. S. Al-Haydari) plastic shrinkage cracks and post-cracking [19] that limit the cracks formation, thereby, extending the concrete service life.…”
