    Rheological behavior of the epoxy resin loaded with the pozzolan
    (2012) Irekti, Amar; Hami, Brahim; Aribi, C.; Bezzazi, B.; Briki, I.
    The study is to synthesize composite materials with news formul ations of thermosetting matrices by the incorporation of 40% of mineral fillers to reduce the cost of composite materials an d to improve implementation by increasing the viscosity and redu cing the withdrawal to its minimum value. The mineral filler increases si gnificantly in rheological parameters, whatever it nature of th e mineral filler. Compared to the control without charges, an increase of 60% of the shear stress and that of plastic viscosity were reco rded for the epoxy resin. The software Rheowine viscometer enabled us to m odel and identified the rheological behavior of these mixtures wit h resin. The results obtained in this modeling, confirmed that th e resin mixtures have shear-thinn ing rheological behavior, this last allows the model of the Ostwald de Waele

    Multilayer system of thermosetting polymers and specific confining : application to the walls of the hospital unit
    (Photon Excellence Award-2014 : The Journal of Materials Science, 2014) Bouzid, Mohammed; Djadi, A.; Aribi, C.; Irekti, Amar; Bezzazi, B.; Halouene, F.
    The nature of materials structuring our health institutions promote the development of germs. The sustainability of nosocomial infections remains significant (12% and 15%). One of the major factors being the portland cement which is brittle and porous. As part of a national plan to fight nosocomial infections, led by the University Hospital of Blida, we opted for a composite coating, application by multilayer model, composed of epoxy-polyester resin as a binder and calcium carbonate as mineral fillers. The application of composite materials reinforce the wall coating of hospital units and eliminates the hospital infectious areas. The resistance to impact, chemicals, raising temperature and to a biologically active environment, gives satisfactory results
