A Novel Method For The Production Of Pig Iron In “Hadisolb” Company (Industrial-Scale Experiments), El-Sayed A. Rassoul

Mansoura Engineering Journal

The chairman of “Hadisolb” had submitted a memorandum in 1977 in which he claimed that the company will never achieve its designed capacity unless it gets rid of the threatening impurities -high alkalis & MnO- in the blast furnace burden. Meanwhile, the DR steel companies are suffering from the generated accumulated wastes which contain > 67% Fe, zero% alkalis and traces of MnO. The novel idea here is finding the best ratio between El-Gedida ore and the waste material (W.M.). In a previous investigation a series of pilot-scale sintering experiments were performed and it was concluded that the blend containing 70% …

Influence Of Macro-Synthetic Fibers On The Flexural Behavior Of High Strength Concrete Beams Reinforced With Gfrp Bars, Maryam M. Koura, Ahmed M. Tahwia, Mohamed H. Matthana

Mansoura Engineering Journal

Rusting of steel reinforcement in marine environments causes the overall destruction of reinforced concrete constructions; steel rebars in concrete members have been replaced with fiber-reinforced polymer (FRP) bars in recent years. To enhance the shear behavior of glass (GFRP) bars reinforced concrete (RC), macro-synthetic polyolefin (PO) fiber was added. These materials have a low modulus of elasticity, a high tensile strength, and a linear stress-strain response to full failure. This study investigates the effect of macro synthetic structural fibers on the post-cracking and deformability properties of high strength concrete reinforced with FRP bars without transverse reinforcement. Eight full-scale RC beams …

Machine Learning-Based Prediction Of International Roughness Index For Continuous Reinforced Concrete Pavements, Ragaa T. Abd El-Hakim, Ahmed N. Awaad, Sherif M. El-Badawy

Mansoura Engineering Journal

The International Roughness Index (IRI) serves as a crucial indicator for ride quality and user comfort. As road roughness escalates, road serviceability diminishes, resulting in reduced vehicle speed and increased travel time, and consequently higher carbon dioxide emissions. Predicting the IRI is of utmost importance for Pavement Management Systems and sustainable development overall. While numerous studies have forecasted the IRI of flexible pavements, there is a notable scarcity of research focusing on rigid pavement performance prediction. This study addresses the gap in predicting IRI for Continuous Reinforced Concrete Pavements (CRCP), an understudied aspect of pavement engineering. Leveraging the Long-Term Pavement …

Environmental Impact Assessment Of Water Desalinating Systems: Kuwait As A Case Study, Eissa S. Al-Mutairi, Ibrahim.G. Rashed, Mohamed.M. El-Halwany, Mohamed A. Mosaad

Mansoura Engineering Journal

The challenge of managing water resources is intensifying due to rapid urbanization, population expansion, and the growth of industry and agriculture. Furthermore, the looming threat of climate change significantly impacts both water resources and crop yields. In Kuwait, the majority of its potable water supply is dependent on seawater desalination. Specifically, multistage flash (MSF) desalination accounts for nearly 90% of the country's total desalination capacity, while the remaining 10% is generated using multi-effect distillation (MED) technology. Nevertheless, the environmental repercussions of desalination on Kuwait's ecosystem remain a subject of profound concern.
