Mechanical properties of compressed earth blocks reinforced with glass fibers and palm fibers: Experiments and simulation

Abstract

The civil and mechanical engineers are interested in studying how much load structures can support. Recently, the use of environmentally friendly materials has become widely spread in the field of construction because they do not contribute to the propagation of greenhouse gases, unlike cement construction. In this research, we try to address the problem of the fragility of clay bricks. We use the compressed earth technique and add palm fibers and glass fibers. We want to know the effect of adding these fibers on density, speed of sound transmission rate, and stresses. Preliminary results show the addition of 0.1%, 0.2%, 0.3%, 0.4%, and 0.5% of palm fibers and glass fibers, respectively. The density value increases between 1.1% and 11%. The speed of sound increases between 2.1% and 13.7%, and the stress value increases between 8.6% and 41%. These results enable us to set limits for the loads supported and borne by the walls built with these bricks.

Advancing Earth-Based Construction: A Comprehensive Review of Stabilization and Reinforcement Techniques for Adobe and Compressed Earth Blocks

“…• Nine articles focused on powder: water hyacinth ash [44], sugarcane bagasse ash [7,35,45,46], and rice husk ash [47][48][49][50]; • Five articles focused on fibers: Pennisetum setaceum [51], plantain pseudo-stem fiber [52], coconut fiber [53], alfa fiber [54] and paper cellulose [55]; • Four items studied other types of waste: wheat and barley straw [27], sargassum muticum seaweed [31], crepidula fornicata seashells [56], and shea butter waste [57].…”

“…As an example, the work of Hussain et al [58] has been funded by the European Union project, Next Generation EU under the France Relance program for the valorization of inert excavated soils (VALODEB) with the collaboration of Unilasalle Rennes and Gendrot TP. Similarly, the research of El Mendili et al [56] was supported by the European Regional Development Fund in the frame of a BLUEPRINT to a Circular Economy project (Interreg V A France (Channel) England, Project n•206).…”

The Utilization of Recycled Concrete Aggregates in Fiber-Reinforced SelfCompacting Concrete

“…We established the S/M ratio at 0.50, the W/L ratio at 0.38, and the Sp/L ratio at 1.5% for each of the concrete mixes that were utilized. Because it ignores the crucial components of admixtures and additions, the Dreux-Gorisse method is deemed inappropriate and impracticable for selfcompacting concrete (SCC) [13][14][15][16][17][18][19]. The majority of self-consolidating concrete (SCC) formulas are currently developed primarily through empirical methods [20][21][22][23][24].…”

Analysis of the use of self-compacting concrete in Algeria: opportunities and challenges

“…Several studies have been carried out by Algerian researchers on concrete mixed with local materials, and these results have given acceptable to good results [10][11][12][13][14][15][16][17][18][19][20][21].…”
