FABRICATION DES BRIQUES POUZZOLANIQUES A BASE DES DECHETS NATURELS {VASE ET FINE CALCAIRE}

Abstract

This work consists of the realization of bricks by the valuation of a natural product that is pozzolan and recycling industrial waste such as marble powder and fine limestone. Our goal is to make a brick that has the characteristics of a silico-limestone brick usually made from sand and lime in an autoclave. The percentages of the different constituents were varied in order to see their effect. The use of dredged mud allows us to significantly reduce their rejection in nature The use of pozzolana reduces the cost of production of the brick. The association between pozzolana and mud gives good results. Key words: silico limestone-pozzolana bricks – dredged silt- lime- limestone- oven
