Research summary
تناولت هذه الدراسة تأثير إضافة ألياف النفايات البلاستيكية الموزعة عشوائيًا على الخواص الجيوتكنيكية للتربة الغضارية. اعتمد البحث على منهجية تجريبية تضمنت مرحلتين: الأولى دراسة خواص عينات التربة الغضارية من منطقتين في سوريا بدون إضافة الألياف، والثانية إضافة الألياف بنسب مختلفة (0.25%، 0.5%، 0.75%، 1%) من وزن التربة الجاف ودراسة تأثيرها على الكثافة الجافة العظمى، محتوى الرطوبة الأمثل، التماسك، وزاوية الاحتكاك الداخلي. أظهرت النتائج أن إضافة الألياف تقلل من الكثافة الجافة العظمى وتزيد من التماسك وزاوية الاحتكاك الداخلي، بينما لا تؤثر على محتوى الرطوبة الأمثل.
Critical review
دراسة نقدية: البحث يقدم مساهمة مهمة في مجال تحسين التربة باستخدام ألياف النفايات البلاستيكية، وهو موضوع ذو أهمية بيئية وهندسية. ومع ذلك، كان من الممكن أن يكون البحث أكثر شمولية إذا تم تضمين المزيد من المواقع الجغرافية المختلفة لتحليل تأثير الألياف في ظروف تربة متنوعة. كما أن الدراسة قد استفادت من تحليل اقتصادي لتكلفة استخدام الألياف البلاستيكية مقارنة بمواد تحسين التربة التقليدية. بالإضافة إلى ذلك، كان من الممكن أن تكون هناك توصيات أكثر تفصيلًا حول كيفية تطبيق هذه النتائج في مشاريع البناء الفعلية.

As a result of the development of the use of reinforced Composites with fibers in practical applications continuously, research aims to study the effect of proportion piroxide additives to unsaturated polyester resin on the tensile properties of th e samples prepared from unsaturated polyester resin reinforced with glass fiber used in wind turbine blades manufacturing, and also studying the effect of for the application of heat treatment operations on the hardening of the unsaturated polyester and tensile properties after heat treatment process the application in order to improve the properties of these blades. Test samples were prepared containing ratios (1% - 1.5% - 2%) of methyl Etel ketone piroxide MEKP and test results showed that the best ratio at 1.5%. While the heat treatment results showed that the best values for tensile strength at break of the samples are treated to a time of / 48 hours /.
This research includes an experimental study for the manufacture of a composite material based on polymer (unsaturated polyester), reinforced with random fiberglass at different weight fractions. By suite, it has been studied some mechanical prope rties of the models manufactured, to determine the effect of glass fiber content on the tensile strength, hardness and impact resistance. This study has shown that the best results were for samples reinforced by 40% fiberglass, where the tensile strength increased about 70%, hardness up to 30%, and impact resistance about 43%. It will be observed that the mechanical properties decrease clearly at 60% of weight fraction of fiberglass. This fact can be related to the quantity of unsaturated polyester become inadequate for recharge of the fibers, which leads to weakness in the forces bonding in composite materials.
The results showed the possibility of getting at a wide rang of board with different properties, and all investigated percentage had special properties which to use in industrial application, also the result showed the possibility to produce these bo ard without pretreatment of particles wood or without addition any virgin plastic to RLDPE The results showed the possibility of getting of a wide spectrum of boards with different properties, and all studied percentages had special properties which allow them to use in industrial application, also the result showed the possibility to produce these boards without treatment of the wood particles or without addition any virgin plastic to RLDPE
This study was conducted during the 2011-2012 and 2012-2013 seasons in Abu-Jarash orchards area in Damascus to identify the effect of improved organic materials as sludge, manure and compost in improving some soil physical characteristics and whea t productivity. Results showed that the three types of organic material affected the physical characteristics of the studied soil. They decreased its bulk density, increased its total porosity and increased its ability of holding water at field capacity. Results also showed that the compost of city wastes was the best in improving soil physical properties. The three organic materials, particularly the sludge increased the total productivity of wheat (Sham3).
Thepaper studies the mechanical properties ofsteel fibers reinforced lightweight concrete.This kind of concrete is produced by usingscoria aggregateswhich can be found abundantly in Syria. Thelightweight concrete mixeswere designed for three differ ent percentage of steel fibers (0, 0.5, 0.75)%. Different tests were performed to determine mechanical properties of product concrete such as compressive strength, elasticity modulus, splitting tensile strengthand flexural strengthalso; the stress–strain diagram of produced lightweight concrete was established under compression. The results showedanincrease of the compressive, splitting tensile and flexural strengths reach up 16.9%, 25.6%, and 53.6% respectivelywhen the steel fibers were used. Also the results indicated the importance of using the steel fibers to improve the performance of concrete and change its brittle behavior to ductile behavior.
