RESUME:- Cette etude porte sur l'activite pouzzolanique des dechets de briques et tuiles cuites recoltes dans trois unites de production de Yaounde et ses environs. La caracterisation des materiaux (argiles lateritiques) bruts des dechets a montre qu'ils contiennent de l'argile kaolinitique peu plastique. Les dechets et ces argiles calcinees a 800 °C ecrases a O

ABSTRACT:- The pozzolanic activity of waste fired bricks and tiles from three production units in and around Yaounde were studied. The raw materials (lateritic clays) of the wastes are kaolinitic and of low plasticity. The clays calcined at 800 °C and the wastes, crushed to fine powders of O Key Words: Fired bricks and tile wastes, wastes recycling, clinker, pozzolans, pozzolanicity, cements, mortars.
