Old Aswan Dam: standing the test of time
Article Abstract:
The Old Aswan Dam in the First Cataract of the Nile in Aswan, Egypt was built between 1898 and 1902 using granite rubble masonry and ashlar masonry. In 1980s, the High and Aswan Dams Authority conducted a comprehensive check-up concerning the integrity and seismic stability of the dam. The physical and mechanical properties of the building materials used were examined through chemical analyses to determine the condition of the dam. In totality, the dam's masonry is relatively stable although few defects such as open-bleed water channels and medium to large cavities were found.

Pyramid power
Article Abstract:
The three large pyramids in Giza, Egypt, were built during the 26th century B.C., using Tura limestone, and mortar containing gypsum and aggregate particles. The limestones are well-fitting megalithic pieces that were probably bashed out of stones rather than cut out. They were placed in position using building ramps. The pyramids show good funeral layout, masonry, and construction methods. The mechanism of mortar formation was primitive, and no limestone was used. Reliefs on the pyramid walls indicate the use of slave labor in their construction.
