摘要：This paper investigates the feasibility of using shells from marine coasts of the SoussMassa region in Agadir (Morocco), as aggregates in the production of a compositematerial called ecological concrete. Different steps were conducted: Firstly, a prospectingphase carried out on various sites of the concerned region in order to identify and quantifythe different types of waste shells available in sites and also to establish a regionalmaritime waste cartography. Then a sort was done, followed by a thermal treatment toeliminate any kind of impurities, and then a crushing was made to the collected shells.Secondly, physical characterizations of different aggregates, including shells, to moreparticularly determine the measurement of bulk density, the apparent particle density andcompactness of shells. A geometric characterization through a particle size analysis wasalso performed. The obtained parameters were compared to those of the sand dune andquarry sand. Furthermore, a study on the chemical characterization on these shells must beconducted.
