Assessment Of Key Imperatives For Enhancing Precast Adoptability In Egypt, Mostafa Sameh

Theses and Dissertations

Precast Concrete’s modular application concept is a major construction method that has been used historically seen in various shapes, forms, and with a wide range of constituents. Examples include Ancient Egypt and China among several impressive structures in old civilizations. The major advantages of precast concrete lie in its adaptability, resilience, and versatility which makes precast concrete one of the most agile building materials. Precast concrete as we know it today has been introduced to our markets over the past several decades. Having similar advantages to that of old precast building methods, the road has been paved for wider use …

Assessment Of Carbon Dioxide Emission And Its Impact On High-Rise Mixed-Use Buildings In Egypt, Ahmed Salah Hamza

Theses and Dissertations

With Egypt's vision of 2030 focusing on sustainable development with a true emphasis on Carbon Dioxide (CO₂) emission reduction in the newly built cities and high-rise buildings, efforts are exerted on various levels towards accomplishing the vision’s goals. This is achieved through multiple tools and models associated with aiding the reduction of carbon emissions, yet not a clear one was introduced for the mixed-use buildings in Egypt.

Through this work, a significant gap was identified with respect to high-rise buildings carbon emission assessment in Egypt. This was a main driving force for this work in an attempt to …

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 …

Underwater Concrete, Dina Adel Nakhla

Archived Theses and Dissertations

Underwater structures represent a significant portion of concrete works worldwide. The utilization of various underwater concrete techniques has indeed minimized the use of costly dewatering processes. Such techniques include the use of special· equipment such as trernie concrete and preplaced aggregate technique. The incorporation of antiwashout admixtures has evolved as a method to minimize the washout of cement and fine particles. As for today, there exists relatively limited information regarding different underwater concreting techniques to facilitate feasible and adequate selection of appropriate methods. This work comprises a survey study and an experimental work to evaluate the impact of using the …
