Behavior Of Two Parallel Strip Footings On A Sand Cushion Over Clay, Mostafa El Sawwaf, Ashraf Nazir, Ahmed Farouk, Shimaa Saied Hashish

Journal of Engineering Research

In this paper, the behavior of two parallel strip footings resting on the surface of a semi-infinite clay is investigated. The effect of stress interference on bearing capacity and settlement are studied using the finite element program PLAXIS 2D. The clay is stimulated using the Mohr-Coulomb soil model that follows linear-elastic perfectly plastic behavior. A parametric study is performed for different clear spacing between the footings. The paper also investigates the effect of existence of a sand cushion as well as the existence of a layer of geogrid inside the cushion below the clay; on the stress-settlement relationship, and the …

Studying The Effect Of Adding Aleppo Pylon To The Properties Of Insulating And Accumulation Of Polyvinyl Chloride Films, A. Habib, Y. Joher, E. Al Haddad, M. Beesh

International Journal of Thin Film Science and Technology

This research presents a study of the effect of adding natural and modified Aleppo Pylon (Syrian clay) in different proportions to the properties of polymeric films prepared from poly vinyl chlorid (PVC) polymer and dried at three different drying degrees (60oC, 100oC, 150oC). The clay surface was changed from hydrophilic to hydrophobic by treating the surface with quaternary alkyl ammonium salts. Both types of Aleppo Pylone were added to the polymer by weight (0%, 2.5%, 5%, 7.5%, 10%), and the polymeric films were prepared by way of mixing well of PVC polymer and clay. The mixing technique used hexanol as …

Microstructure And Damage Assessment Of Some Ptolemaic Pottery Objects At Tell Abu Yasin In Sharkia, Egypt: Case Study, Walid ᾿El-Ghareb ᾿El-Ghareb

Journal of the General Union of Arab Archaeologists

(En)

Tell Abu Yasin is one of the most important sites in Sharkia governorate and dates back to Ptolemaic age. Many tests and analyses were performed to diagnose damage manifestations of some pottery pieces. The research has proven that the clay used in that pottery is Nile Clay, while tempers are sand, grog, and limestone powder. The used shaping technology was potter wheel, surface treatment is slip layer, and the burning atmosphere inside the kiln was reduced for the first pot and oxidized to the second and third piece. Pottery objects suffer from physiochemical damage by soil sediments, in addition …
