“…Similar results were obtained by [15,20]. El Messiry et al [20] reported that the flexural properties of jute fabric reinforced cementitious composites increases as the fabric layers increased from 1 to 3. In addition, Colombo et al [15] observed that the tensile strength of the concrete reinforced with textile fabric increased from 11.36 MPa to 24.42 MPa at the textile fabric layers increased from 1 to 2.…”

The utilization of plant based (natural) fabrics as reinforcement in composite materials is fast growing in the engineering field, due to their environmental friendliness and appreciable mechanical properties. This study was carried out to evaluate some flexural properties (flexural strength and flexural deflection) and water absorption rate of raffia palm fabric reinforced cement composite samples. Ordinary Portland cement (grade 42.5N) was used as the binding material. Cement to fine aggregate (450 µm) mix ratio of 1:3 (by weight) was employed for the composite production, while a water to cement ratio (w/c) of 0.4 was adopted. For the purpose of this study, cement composite beams were reinforced with raffia palm fabrics in 1-fabric, 2-fabrics and 2-layer configuration. All the cement composite samples were prepared and tested in accordance to ASTM standard procedures. Results from the flexural tests showed that the flexural properties of the composite samples were highly influenced by the raffia palm fabric reinforcement. The composite samples reinforced with 2-layers generally had higher flexural properties, when compared to the results obtained from the composite reinforced with 2-fabrics and 1-fabrics reinforcement. The ultimate flexural deflection attained in the 2-fabrics and 2-layers configurations were comparable, but slightly highly in the 2-layers. A mean deflection of 6.12 mm was recorded in the composite reinforced with 2-layers, which was higher than the mean deflection of 5.56 mm recorded for the composite reinforced with 2-fabrics. For all cases, the unreinforced cement composite (control Samples) had the poorest flexural properties. In terms of the water absorption rate, the 2-layers fabrics composite samples had the highest water absorption rate when compared to the 1-layer fabric reinforced composite samples and the control samples. These results will be useful in the building industry and in the design and development of natural fabric reinforced concrete structures.

“…The use of natural fibers in cementitious matrix composites can considerably improve the physicalmechanical properties of the material [4,5,[7][8][9], can significantly reduce the material cost [10,11], and can reduce the environmental impact caused by the production process of the mixing materials [12]. Consequently, several configurations of natural fibers have been mechanically explored in cement-based composites, such as the textile form [13][14][15], short and randomly dispersed in the matrix [16][17][18], or in a continuous and aligned way [19][20][21]. Despite the benefits cited, natural fibers have a high ability to absorb moisture [22] and may develop durability problems when in the alkaline environment of the cement matrix [1,23].…”

On the mechanical properties and crack pattern analysis of a strain-hardening cement-based composite reinforced by natural sisal fibers

et al. 2022

Besides the strength enhancement and strain improvement (strain-hardening behavior), the use of natural fibers as reinforcement in cement-based matrices can also be highlighted as an economical and eco-friendly alternative for the future of the construction industry. In the present work, cement-based composites reinforced by natural sisal fibers were produced and tested under direct tensile loading. The Portland cement was partially replaced by pozzolans (metakaolin -MK and fly ash -FA), aiming to produce a calcium hydroxide-free matrix to ensure the durability of the fibers. The natural sisal fibers were used in a 5% volume fraction (in mass), divided into three layers. The mechanical properties of composite plates were compared to other literature results and demonstrated to be compatible with recent research. The crack pattern was analyzed by Digital Image Correlation (DIC) for a better understanding of their failure mechanisms. The material presented a tensile strength increase after the first crack formation, marked by multiple cracking partners from this point. Finally, a comparison between direct (LVDTs) and indirect (DIC) methods of strain measurement was done and demonstrated minor results for the DIC, approximately 84% of those obtained from the LVDTs.
