Performance Of Self-Compacting Concrete, Mohamed Samir Rushdy

Archived Theses and Dissertations

Concrete compaction is one of the indispensable fundamentals of concrete manufacturing. However, thorough compaction cannot always be insured. This can be wholly or partially encountered in congested sections, out-of reach deep foundations and narrow or irregular precast components. On the other hand, typical vibrators were considered as contributor to health hazards to workers. Self-compacting concrete (SCC) is an emerging concrete where the cohesive yet flowable consistency of the concrete itself secures adequate placement with high level of homogeneity and little or no segregation. Such concrete is primarily achieved by incorporating admixtures that is referred to as viscosity modifying (VM) admixtures …

Neural Networks For Estimating The Productivity Of Brick Works And Plastering Works In Egypt, Mohamed Aly Masoud

Archived Theses and Dissertations

Neural networks have proven apparent success in solving a wide variety of problems. Various engineering applications in particular were studied using these powerful tools.

The Neural network resembles the function of the human brain. A training

process has to be applied first in order that the network acquires knowledge through learning. Then the network can generalize predicted solutions based on the a mount and accuracy of the training data. The target of this research is to develop two neural networks that can predict the productivity of two common construction-finishing activities, which are brick and plaster works. In order to adequately …

Construction Of Shopping Malls In Egypt, Ramez Wageih Shafik

Archived Theses and Dissertations

This thesis entitled "Construction of Shopping Malls in Egypt: Reasons For Delay and Estimated Duration" was prepared by Ramez W ageih Shafik under the supervision and guidance of Dr. Samer Ezz El Din at the American University in Cairo The construction industry is one of the most important and essential industries in the economy of any country. Time delay is one of the major problems facing the construction projects in Egypt. Facing the fact that the construction of shopping malls has picked up in Egypt during the last ten years, research is needed to identify the different factors that affect …

Recycled Concrete Properties And Feasibility, Mourad Nabil Shenouda

Archived Theses and Dissertations

As conventional good quality aggregates are becoming scarce in some zones in Egypt and many areas worldwide, and as environmental concerns are raised on dumping old and fresh concrete in landfills, recycled concrete has been receiving increased interest worldwide for its potential environmental, economic and technical merits. In fact, many countries have adopted such concrete in their codes and the majority of their old concrete is being recycled. An attempt is being made to trigger factors and means that enhance the economic feasibility of recycled concrete. The overall goal of this work is to pinpoint strength and deficiencies in this …
