PhysiqueTags : Geomaterials limestone clay porosity moisture Géomatériaux calcaire porosité humidité construction مواد صخرية الكلس الطين الفراغات والرطوبة Index. décimale : 530 Physique Résumé : The objective of this work is the physico-chemical and mechanical geomaterials limestone (white and gray) and clay. Two local raw materials are abundant. The first extractionis from the region of Jebel KELLAL and the second is from the region of Jebel Ouahch in province of Constantine.
After the samples preparation in powder form for limestone and clay, and sugar on glass slides, we have implemented various analytical techniques to better understand their properties: the X-ray diffraction, optical microscopy and scanning electron microscopy, the measurement of the microhardness, the measurement of the water porosity and measurement of moisture content.
The results of our work revealed that the white and gray limestone of Jebel KELLAL are very good qualities they possess important physico-chemical and mechanical. Therefore, they will be very useful in the construction and restoration.Diplôme : Magistère En ligne : ../theses/physique/KHE6308.pdf Format de la ressource électronique : Permalink : index.php?lvl=notice_display&id=9528 Caractérisation physico-chimique des géomatériaux [texte imprimé] / Samia Kherfi, Auteur ; Merzoug Bouchear, Directeur de thèse . - Constantine : Université Mentouri Constantine, 2012 . - 95 f. ; 30 cm.

Sciences de la terreTags : Sciences Géologiques: Géo-ressources et environnement Altération dégradation sels calcaire tufs Weathering Degradation Salt crystallization Limestone Tufas التغيير التدهور الأملاح الحجرالجيري الأحجار الكلسية Index. décimale : 550 Sciences de la terre Résumé :
The Byzantine wall and the Roman basilica are the main representative examples of historical sites in Tébessa (North-eastern Algeria), which pink limestones of Middle Turonian and carbonate tufas are the most used construction materials. In-situ investigations have shown the most common weathering forms are flaking, alveolisation, efflorescence, fracturing, discoloration, white crust, dusting, powdering and granular disintegration. These weathering forms are produced by the salt action (Gypsum and Halite) which are related to the petrophysical and textural properties of pink limestones and carbonate tufas. Quantification of degrees of weathering using physico-mechanical properties revealed that degradation is characterized by a decrease in density and increased porosity for pink limestone, while carbonate tufas are characterized by a decrease in density with the decrease in porosity. Schmidt's hammer revealed that the damage is medium to severe in both monuments studied.
The petrophysical properties and durability are measured for both stone types which extracted from quarries. Porosity, capillary absorption coefficient, ultrasonic waves and uniaxial compression are used to characterize the petrophysical properties, and the salt crystallisation tests is used to estimate their durability. These properties are closely linked to the microstructure of the stone. Carbonate tufas show excellent durability under salt crystallization and lower mechanical strength than limestone. Limestone, on the other hand, despite its lower porosity and better mechanical strength, show lower durability values. While micropores contribute to the relatively lower value of sustainability; in tufas, macropores reduce the saline action on the porous structure and increase its durability. Our investigations have shown that the Byzantine wall and the Roman basilica require urgent conservation measures. Finally, in the ancient constructions of Tébessa, the pink limestone will be the most degraded than the carbonate tufas.Note de contenu :

Sciences de la terreTags : Calcaire dolomie géologie prospection applications chaux nord-est Algérie Limestone dolostone geology exploration lime North-Eastern Algeria الكلس الدولوميت الجيولوجيا الإستكشاف تطبيقات الجير الشرق الشمالي الجزائري Index. décimale : 550 Sciences de la terre Résumé : This study is a contribution work intended to make known the lime as well as its production sources; limestone and dolomite.
Raw materials quality is a prerequisite to obtain a good and effective product. For this purpose, four active quarries have been selected; these quarries are situated in quite different geological environments of northeastern Algeria.
For limestone: Djendel career and terraced Ben Azzouz career, both located in the “prékabyle” area near Skikda have been selected as well as Khroub quarry known for its production of high quality calcium carbonate. For dolomite, Téioualt career near Aïn M‟lila is taken into account. The last two careers are part of Constantine‟s neretic formations.
Such working sites are each discussed in the local geological and mining context. All their products serve – currently Djendel and Teioualt - or have served temporarily, the lime plant of El Hadjar steel complex.
Based on field observations and taken samples, several chemical analyzes, cooking tests and other characterizations tests were carried out.
The results confirmed the adequacy of samples physico-mechanical and thermal properties and their suitability for lime manufacturing. The obtained results validated Djendel and Ben Azzouz ability to continue to fill the needs of steel industry. The limestone reserves; quite abundant in Djendel; could allow, in case of qualitative failure to carry out a selective exploitation. The Ben Azzouz‟s limestone bench overcomes a dolomitic sitting that could be interesting to prospect...
For Khroub limestones and Téioualt dolomites, the results are even more conclusive. For these substances, and beyond the steel industry, other uses are possible: water treatment and other applications, this should be confirmed by specific feasibility tests ... But in terms of quantity and in the eventuality limestone units will be selected, new possibilities should be highlighted near these sites as long as the same qualities and the same basic material homogeneity still continue. Appropriate assessment should be conducted in this way.
For raw materials, especially limestone, many north eastern Algerian sites should be promoted. Carbonate sets from Cretaceous and Jurassic periods are most favorable for investigations. The assessments should target rather organogenic formations of marine origin, platform or reef type, whose deposits were held in quiet and shallow areas... as long as the deposits are sufficiently thick, homogeneous and undisturbed by tectonic...
Produce some varieties of lime needed for the most critical current needs seems to be a strategic choice within the scope of sustainable development...
