Current research in the field of building materials is oriented towards the recovery of waste to ensure the lightening of certain building elements and energy saving. The objective of this study is to produce a new bricks by adding sawdust to clay mixtures. The first part of this experimental work consists on detremining the proper manufacturing process and cooking diagram for these new bricks. In the second part, the effect of the maximum cooking temperature, the firing phase time's of the bricks and the sawdust prportion on the physical and mechanical properties of the new bricks have been studied. The studied properties are the absorption ratio, the unit weight and the compressive strength. The results showed that the addition of an increasing amount of sawdust tends to modify the physical and mechanical properties of the cooked samples. The presence of sawdust reduces the number of connections between the clay grains and produces a lighter, more absorbent and less resistant material. Finally, the results showed that the manufacture of bricks based on sawdust is possible.
Résumé
La recherche actuelle dans le domaine des matériaux de construction est orientée vers la valorisation des déchets pour assurer l’allégement de certains éléments de construction et une économie d’énergie. L'objectif de cette étude est de produire des nouvelles briques d'argile plus légères que celles qui sont actuellement sur le marché, en ajoutant des sciures de bois aux mélanges d'argile. Plusieurs paramètres ont été étudiés ainsi que leur effet sur les modifications des propriétés physiques et mécaniques tels que le taux d’absorption, la température maximale de cuisson, la proportion des sciures et la durée de la phase de cuisson de ces briques. Un processus de fabrication, de séchage et de cuisson a été adapté au nouveau produit. Les résultats ont montré que l'addition d'une quantité croissante de sciures tend à modifier sensiblement les propriétés physiques et mécaniques des échantillons cuits. La présence de sciures réduit le nombre de connections entre les grains d'argile et produit un matériau plus léger, plus absorbant et moins résistant. Enfin, les résultats ont montré aussi que la confection des briques à base des sciures de bois est possible.
