Effect of Incorporation of Chips and Wood Dust Mahogany on Mechanical and Acoustic Behavior of Brick Clay

Abstract

An experimental study was carried out on bricks using local materials in order to take into account the waste wood management to protect the environment and to reduce the cost of the habitat. Chips and sawdust were built-in clay bricks in order to study their influence on the compressive strength, Young's modulus and the speed for soundproofing. Testings in compressive strength were made on the parallelepiped clay bricks, stabilized with different percentages of cement, with incorporation to various percentages of sawdust or wood chips (Mahogany), using a universal press. Young's modulus was measured from the speed of sound by the ultrasonic method. The results obtained show that the incorporation of mahogany tree chips in the stabilized brick at 8% of cement, does not have much effect on the compressive strength. It was found that the incorporation of chips or sawdust on the clay brick, does not improve the compressive strength. The Young's modulus decreases with increasing content of sawdust and practically remains constant regardless of the content of chips at 4% and 6% of cement. The clay brick mixed with 8% of mahogany sawdust can be an acoustic barrier.

Impact of pH Water and Mineralogical Microstructure of Soil Mixed with Wood Waste on the Compressive Strength of Composite Bricks; and Bricks Resistance Modeling

“…Most of these works, as shown by the studies of [1]- [9], focused on the influence of this waste on the mechanical, thermal and acoustic properties of earth concretes. It has been noted in this work that the incorporation of the chips and sawdust in the blocks of cement-stabilized ground, involves a considerable reduction in the mechanical properties of these composite materials compared to the blocks of stabilized ground (0% of wood) [10]. This decrease has been interpreted in terms of physico-chemical exchanges between wood waste and clay.…”

Effect of Wood Waste on Acoustic and Magnetic Properties of Composite Bricks and Correlation between Sound Velocity and Magnetic Induction in These Bricks

“…Today, several researchers as Khelifi, Taoukil and Tamba [4] [5] [6] showed in their work that wood can be used in the form of waste (chips and sawdust), incorporated at different contents in clay bricks (CB). Most of these works are focused on the impact of wood waste (WW) incorporated in earth blocks on mechanical, thermal and acoustic properties of CB as shown by the work of: Ganga, Salif and Meukam [7] [8] [9] [10] [11]. The air stored by the wood waste embedded in the earth bricks, leads to an increase in the porosity of these composite bricks according to the content of wood waste.…”

Quality evaluation of soil-cement-plant residue bricks by the combination of destructive and non-destructive tests

“…Because of the problem of searching adequate disposal, recent studies have reported the use of agro-industrial residues in the manufacture of pressed bricks (Faria et al, 2012;Madurwar et al, 2013;Zhang, 2013;Ganga et al, 2014;Laborel-Préneron et al, 2016).…”

“…Likewise, quality can be evaluated through non-destructive tests, such as the ultrasonic wave propagation technique (Cazalla et al, 1999;Qasrawi, 2000;Cultrone et al, 2001;Ferreira & Freire, 2004;Brozovsky, 2014;Carrasco et al, 2014;Ganga et al, 2014). Cultrone et al (2001), studying the influence of different raw materials on the quality of fire bricks, proposed the concept of "anisotropic resistance" as a quantitative parameter to evaluate brick quality, combining the results of simple compression (destructive method) and structural anisotropy (non-destructive method).…”
