Manufacturing processes are the main source of waste materials, however the increasing awareness about the environment has tremendously contributed to the concerns related with disposal of the generated wastes. Solid waste management is one of the major environmental concerns in the world. With the scarcity of space for land filling and due to its ever increasing cost, waste utilization has become an attractive alternative to disposal. Research is being carried out on the utilization of waste products in concrete. Such waste products include discarded tires, plastic, glass, and coal combustion by-product. This paper presents a detailed review about recycled plastics (polyethylene), as aggregates to cement mortar by replace equivalent weight of sand by plastic in regular specimen and watch its effect on the property of mortar include compressive strength, splitting tensile strength, absorption and heating effect. It is clear that compressive strength, splitting tensile strength decreased with increase in plastic content but this property increases by exposing samples to high temperatures.

Research summary
تتناول هذه الدراسة تأثير استخدام النفايات البلاستيكية المعاد تدويرها (البولي إيثيلين) كمضاف للمونة الإسمنتية. يتم استبدال أوزان مكافئة من الرمل في عينات المونة بالمادة البلاستيكية، ومراقبة تأثيرها على خصائص المونة من حيث المقاومة على الضغط البسيط والشد بالانعطاف والتشرب الأقصى بالماء ومقاومة الحرارة المرتفعة. تظهر النتائج انخفاضاً في المقاومة على الشد بالانعطاف والضغط البسيط مع زيادة نسبة النفايات البلاستيكية، وزيادة في قيمة التشرب بالماء. ومع ذلك، تسجل النتائج زيادة ملموسة في المقاومة على الشد بالانعطاف والضغط البسيط بعد تعريض العينات للحرارة المرتفعة. الدراسة تشير إلى أن استخدام النفايات البلاستيكية يمكن أن يساهم في إنتاج مونة خفيفة الوزن، مما يقدم حلاً بيئياً واقتصادياً لإدارة النفايات البلاستيكية.
Critical review
دراسة نقدية: تقدم هذه الدراسة إسهاماً مهماً في مجال إعادة تدوير النفايات البلاستيكية واستخدامها في صناعة المونة الإسمنتية. ومع ذلك، هناك بعض النقاط التي يمكن تحسينها. أولاً، لم يتم التطرق بشكل كافٍ إلى الآثار البيئية الطويلة الأمد لاستخدام البلاستيك في المونة الإسمنتية. ثانياً، لم يتم دراسة تأثير هذه المواد على المدى الطويل من حيث التحلل والتفاعل مع العوامل البيئية المختلفة. ثالثاً، كان من الممكن تقديم مقارنة أكثر تفصيلاً مع المواد التقليدية الأخرى المستخدمة في صناعة المونة الإسمنتية. على الرغم من هذه النقاط، فإن الدراسة تقدم نتائج مشجعة وتفتح آفاقاً جديدة لاستخدام النفايات البلاستيكية في التطبيقات الهندسية.

The accelerated structural expansion in most countries has resulted in a major problem related to providing the necessary concrete for these buildings. Besides, the buildings that have become out of service recently has posed a real problem represent ed in demolishing them creating a large amount of hard-to-manage aggregate. The necessity to get rid of the aggregate have opened up the possibilities for attempting to use it as a relative substitute for the natural aggregate. The research focuses on recycling these aggregate in an attempt to use them in producing concrete and other construction materials. The research deals with one of the mechanisms of benefiting from these recycled aggregate through using them in producing concrete through treating the aggregate produced from demolition, and mixing them in quantities that reflect their actual ratio. The results are of great importance economically and environmentally.
This paper focus on studying the elastic of modified cement mortar by polyethylene (stress-strain) curve in order to have Young's elastic modulus, this made by tri-phases modeling that allow to determination the property of this item depending on t he property of it's three components individual. The validation of the proposed model has been studied extensively depending on a sample of cement mortar divided into two groups, the first one patterning normal cement mortar, second patterning modified cement mortar by Polyethylene witch substitute five percentage ratio of weight of sand by the same ratio of Polyethylene. Modified cement mortar is treated as composite of three components, Sand, Paste cement and Polyethylene. It's will be proposed models involving series, parallel and series-parallel coupling. This composite action is described by series-parallel model in which a portion of paste acts in parallel with sand and polyethylene and the remaining portion in series with this parallel coupling. Then according to the model we get Young's elastic modulus theoretically, reliance basic modulus factors of components. The proposed model is calibrated and verified by means of data set by experiment modulus results perform on cast samples in laboratory. It was found quite agreement of measured modulus factors experimentally versus theoretically.
Plastic and rubber products considered of being a great importance to humans, but their residues and wastes are a real environmental disaster. They are dumped in fields, streams and forests or buried in large landfills that pose a serious hazard th at needs to work on solve it in the best possible way. On the other hand, the economic problems caused by the erosion of concrete cement have made it the major problem of infrastructure in the industrialized countries. Over the past three decades, this problem has reached alarming proportions, which led to high repair costs, whether in concrete or in reinforcing steel, Especially acidic media due to concrete permeability of acid rainwater, where these costs exceeded initial construction amounts in some cases. This paper deals with the recycling of used tires and some types of plastic waste to be used in the preparation of insulating materials for water and heat at a low cost compared to the insulation materials currently used in the construction process, in addition to the preparation of floor tiles for internal and external use.
The large increase in the volume of demolition concrete waste and its impact on the environment has led to reconsider of using concrete demolition rubble as a partial or a whole alternative of natural aggregates to produce new concrete which has th e required properties to use in engineering constructions[1]. With the possibility of improving the mechanical properties of this concrete by processing this aggregates before using it or support this concrete with fiber to improve its structural behavior. This research deals with the study of the replacement the natural aggregates used in concrete with recycled concrete aggregates resulting from the demolition rubble , according to different replacement ratiosranging between 0 % -25 % -50 % -75 % -100% and the impact on the concrete behavior with a natural aggregates and determine the optimal replacementpercentage. The results showed a relative decrease in the concrete resistance on the simple pressure , limited decrease in the volumetric mass also, and a slight adjustment to the behavior of concrete under the loading effect by increasing the replacement proportion of the natural aggregateswith recycled concrete aggregates..
In this research a study was carried out to evaluate the effect of adding random distribution plastic waste fiber inside soil on the geotechnical properties of clayey soil. The research is based on experimental method through many stages.
