Performance Of Self-Compacting Concrete, Mohamed Samir Rushdy
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 …

Archived Theses and Dissertations
Concrete is one of the most resistant construction materials to heat and fire. It is known to retain heat for a relatively long time, thus limiting crack propagation from penetrating deeply. Furthermore, it can be repaired if exposed to fire for a limited time. However it loses its strength dramatically when exposed to elevated temperatures for long duration. With the increase in the use of concrete in structures, a demand arises to assess the fire resistance of concrete structural members and to develop means of improving the fire characteristics of these elements. One of the methods to increase the fire …

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 …
