    Study Of Pathological Cases In The District Of Zguegue Elhedjaj In Laghouat
    (University of Eloued جامعة الوادي, 2015-01-01) Damene, Z.; Goual, M.s.; Bourzgue, T.; Daikh, Y.
    Laghouat is one of the prestigious Saharan cities of Algeria who inherits an architectural and urban heritage (habitat) of national importance. Zguegue El Hadjaj is one of the oldest quarters reflecting the historical and cultural value of the city. He is now in a very advanced state of degradation threatening the health, comfort and safety of its occupants. As part of the rehabilitation of old buildings and to preserve the historical heritage, this study is to identify the different forms of damage in this neighborhood and try to implement an approach to diagnosis and intervention suggestion on some pathologies. Our goal is not to solve all the problems, by cons we present the state of play in this neighborhood and the outlines of a rehabilitation technique through our acquired knowledge, which will serve as a reference tool and encourage the various actors to safeguard this heritage.

    Study Of The Effect Of Aluminum Content And C / S Ratio On The Physico-mechanical And Thermal Properties Of A Lightweight Concrete Made From Sand Dune
    (University of Eloued جامعة الوادي, 2014-07-01) Damene, Z.; Goual, M. S.; Saiti, I.; Benhassine, N.; Ferhat, A.
    This research is a contribution to the development of local materials especially in the development of a cellular concrete with dunes sand. This is an experimental study whose objective is to see the influence of the C/S (dosage of cement compared to sand) and the dosage of aluminum on the physico- mechanical and thermal performance of lightweight concrete cellular type. The results showed that the cement compared to the sand has a remarkable effect on the reaction and that on expansion the mechanical behavior as well as the dosage of aluminum in the composition of cellular concrete has a certain threshold Aluminium beyond which provides no relief benefits. Based on these results, the cellular concrete made from sand dune can be classified as light structural concrete with insulation suitable for very hot and arid environment of our region power.
