“…In the case of the flexural strength of coconut-fiber-reinforced cementitious composites, most studies have reported increased flexural strength [243][244][245][246]272]. In a similar way, the majority of studies have reported enhancements in the flexural strength of jute- [247,248,251,273,274] (Figure 18d), hemp-[252-254] (Figure 18e), sisal- [4,256,275] (Figure 18f), pineapple- [83,258,260] (Figure 18g), sugarcane-bagasse- [4,263,275] (Figure 18h), and flax- [264][265][266][267] (Figure 18i) fiber-reinforced cementitious composites, compared to control specimens/composites. Overall, it may be concluded that, in comparison to compressive strength, the effect of fiber is more significant with respect to enhancements in the flexural strength of cementitious composites.…”

“…The percentage differences in the compressive strength of pineapple, sugarcane bagasse, and flax fibers are shown in Figure 18g-i, respectively. In most of the reported studies, enhancement in the compressive strength was observed with respect to reference composites [83,[258][259][260][261][262][263][264][265][266]. However, Sawsen et al [267] reported reduced compressive strength for flax-fiber-reinforced concrete.…”

Sustainable development involves the usage of alternative sustainable materials in order to sustain the excessive depletion of natural resources. Plant fibers, as a “green” material, are progressively gaining the attention of various researchers in the field of construction for their potential use in composites for stepping towards sustainable development. This study aims to provide a scientometric review of the summarized background of plant fibers and their applications as construction and building materials. Studies from the past two decades are summarized. Quantitative assessment of research progress is made by using connections and maps between bibliometric data that are compiled for the analysis of plant fibers using Scopus. Data refinement techniques are also used. Plant fibers are potentially used to enhance the mechanical properties of a composite. It is revealed from the literature that plant-fiber-reinforced composites have comparable properties in comparison to composites reinforced with artificial/steel fibers for civil engineering applications, such as construction materials, bridge piers, canal linings, soil reinforcement, pavements, acoustic treatment, insulation materials, etc. However, the biodegradable nature of plant fibers is still a hindrance to their application as a structural material. For this purpose, different surface and chemical treatment methods have been proposed in past studies to improve their durability. It can be surmised from the gathered data that the compressive and flexural strengths of plant-fiber-reinforced cementitious composites are increased by up to 43% and 67%, respectively, with respect to a reference composite. In the literature, alkaline treatment has been reported as an effective and economical method for treating plant fibers. Environmental degradation due to excessive consumption of natural resources and fossil fuels for the construction industry, along with the burning of waste plant fibers, can be reduced by incorporating said fibers in cementitious composites to reduce landfill pollution and, ultimately, achieve sustainable development.

As concrete being widely used in the field of construction, the demand for the materials used is increased rapidly. To meet the growing demand it is necessary to use alternative materials to meet the requirements. The Pineapple leaf fibre (PALF) is a highly available material in larger quantity with lesser water content and higher fiber content which makes it as a desirable material as natural fibre. The workability characteristics of Self compaction Concrete (SCC) like flowability, filling ability, passing ability, resistance to segregation and bleeding of concrete were out by using slump cone, U-box, L-box, V-Funnel and J-ring test. The test result shows satisfactory results on the workability of SCC. The fresh and hardened properties of concrete were found at the ages 7 days, 14 days and 28 days for various addition of PALF and various replacements of granite powder with the fine aggregate. The addition of PALF has achieved maximum compressive strength and split tensile strength in all ages of concrete at PALF0.2. The replacement of granite powder with fine aggregate seems to be promising in achieving the maximum compressive strength and split tensile strength at the 10% of replacement.

Alkali Treatment was done on the dry Pineapple leaf fibers using three different percentage of NaOH concentration, 3%, 5% and 7 % for 2 hours at 80°C to remove the unwanted soluble cellulose, hemi cellulose and lignin as shown in table 3.…”

This paper presents the possibility of using pineapple leaf fibers (PALF) in construction industry. In this study each leaf of the plant of pineapple contained 2.5% to 3.5% of strong white silky fibers. PALF were extracted from the pineapple leaves after harvesting the fruit. An average of the three ages, 1month, 2months and 3months was 30 units of pineapple leaves weighed 3 kg for each age. The reported fiber yield of 1month, 2months and 3months were about 6.64 %, 7.48% and 7.70% of fibers respectively. The extraction of 100 kg of leaves yielded 6 kg of the PALF by the process of shredding using the mechanical methods. the reason for overwhelming attention on the natural resources materials are due to large scale agricultural production annually in the world market for example, pineapple is the most cultivated fruits in Africa. Pineapple fruit is cultivated in the world wide approximately land area of 2.2 million km2. 600 thousand tons of PALF can be extracted from agro waste leaves after harvesting of the fruits, Pineapple leaves are not even suitable for cattle feed and after harvest of fruits the disposal of leaves becomes a serious environmental problem. Therefore this research aim is focused on reducing the waste disposed to landfills by extracting the leaves of pineapple.
