DEVELOPMENT OF A MORTAR BASED ON COAL MACHEFERS POWDER

The industrial zone of Jorf Lasfar in El Jadida, has several industrial units that have generated significant volumes of by-products. Among these units, the JLEC thermal power plant, called TAQ MAROC, which stores more than 640 thousand tons of solid residues by a constitution of two types of ashes: hearth ashes and fly ashes. The latter is used in cement production, while the former remains in landfill and has never been reused.Our contribution in this study is to combine the use of natural porous materials (sand) with industrial waste (bottom ash). The aim is to valorise them and give them a second life in the construction field.
