Behavior of Concrete Reinforced with Date Palm Fibers

Abstract

In recent decades, researchers have begun to investigate innovative sustainable construction materials for the development of greener and more environmentally friendly infrastructures. The main purpose of this article is to investigate the possibility of employing date palm tree waste as a natural fiber alternative for conventional steel and polypropylene fibers (PPFs) in concrete. Date palm fibers are a common agricultural waste in Middle Eastern nations, particularly Saudi Arabia. As a result, this research examined the engineering properties of high-strength concrete using date palm fibers, as well as the performance of traditional steel and PPF concrete. The concrete samples were made using 0.0%, 0.20%, 0.60%, and 1.0% by volume of date palm, steel, and polypropylene fibers. Ten concrete mixtures were made in total. Compressive strength, flexural strength, splitting tensile strength, density, ultrasonic pulse velocity (UPV), water absorption capability, and water permeability tests were performed on the fibrous-reinforced high-strength concrete. With a 1% proportion of date palm, steel, and polypropylene fibers, the splitting tensile strength improved by 17%, 43%, and 16%, respectively. By adding 1% fiber, flexural strength was increased by 60% to 85%, 67% to 165%, and 61% to 79%. In addition, date palm fibers outperformed steel and PPFs in terms of density, UPV, and water permeability. As a result, date palm fibers might potentially be employed in the present construction sector to improve the serviceability of structural elements.

Effect of thermal cycles on the engineering properties and durability of sustainable fibrous high-strength concrete

“…The physical properties of PPF were given by the supplier, as shown in Table 5. Frontiers in Materials frontiersin.org 2.1.3.3 Date palm fibres DPFs were obtained from 15-to 25-year-old date palm trees in and around Najran, Saudi Arabia (Althoey et al, 2022a). These trees constitute one of the most accessible diversities and are responsible for a significant volume of agro-waste.…”

Investigation of the Physical Mechanical Properties and Durability of Sustainable Ultra-High Performance Concrete with Recycled Waste Glass

“…It has additionally been observed that glass will begin to display pozzolanic behaviors if the diameter is less than 150 microns; moreover, the pozzolanic behaviors will improve if the particle diameter is reduced to less than 35 microns, leading to better outcomes than 150 micron-sized particles [40]. In brief, according to the findings of several researchers, trash may be effectively used as a binding ingredient in concrete [41][42][43] and GW may be reused in concrete without compromising its quality in any way [44], but while also improving the mechanical performance of concrete [45] and enhancing its durability [46][47][48].…”

Flexural behaviour of RC one-way slabs reinforced using PAN based carbon textile grid

“…Consequently, research on the strengthening of RC slabs using the TRM, are rather limited in the open literature (Loreto et al, 2014;Koutas and Bournas, 2017;Althoey et al, 2022;Çelik et al, 2022). Loreto et al (2014) studied the behavior of an RC slab with an externally reinforced fabric (PBO) reinforced cementitious matrix layer on the tension face.…”
