It is well known to all of us that water plastic bottles waste has become a major problem to the environment. At the same time, incorporating the fibres in concrete like polypropylene is advantageous as they improve its ...

Roadways play a main role in the development of the countries and societies by providing the essential links between the different parts of the country, to facilitate the transport of goods and movement of people. Compaction ...

Flow fluid between moving parts is providing the damping force. Such characteristic can be utilized to build fluid dampers for a wide variety of vibration control systems. Most previous works have studied the application ...

The bonding that exists between the old concrete and the new concrete depends largely on the quality of substrate surface preparation. The accurate representation of substrate surface roughness can help determine very ...

Compaction is the process of mechanically densifying a soil which increase its density to meet engineering requirements. Unstable soils can create significant problems for pavements or structures ,therefore soil stabilization ...

جزء كبير من الخرسانة في حالتها الطازجة والزائدة عن الكميات الفعلية المراد صبها تتحول إلى مخلفات صلدة مما يترتب عليه تكلفة عالية لإعادة تدويرها في هذه الحالة، وإذ تعتبر الخرسانة ثاني أكثر مادة استهلاكاً بعد الماء عليه فمن ...

This research work focuses on the effect of Libyan Kaolin clay particle size on the reheological, surface and mechanical properties of high density polyethylene (HDPE)/clay nanocomposites. Three polymer clay nanocomposites ...

Journal bearings are widely used to undertake a wide range of operating conditions. Under high radial load, low rotating speed and thin lubrication films, asperity collisions between the journal and the bearing surfaces ...

In this work, the effects of sweep applied to rotor of axial flow turbomachines were investigated by means of applying computational fluid dynamics (CFD) tools. Low-aspect-ratio rotors of positive sweep (PSW) have been ...

Geotechnical engineers face serious problems when construction sites contain collapsible soils, which are known by their strength when dry and experience sudden excessive settlement when inundated. Response-to-wetting ...
