Ground improvement as a result of stabilization with cement has its impact on soft soils such as sandy clay in engineering constructions. Stabilized soils are also used in foundation design, where improvement of mechanical properties is needed. Because of these reasons, knowledge of physical and mechanical properties is needed. The relationship stress – strain of soils stabilized with cement is often unclear and strength characteristics need to be clear. In this paper results of physical and mechanical properties soil stabilized with cement are presented.

The distribution and abundance of dinoflagellate cyst assemblages were investigated in surface sediments from south-western Red sea coasts of Saudi Arabia at six sites during March 2010. A total of 19 taxa of dinoflagellate cysts were identified from all sites. The sampling sites showed a similar cyst assemblage, but they differed in total cyst abundance (3 to 4083 cysts g−1 dry weight). Cyst abundance was strongly correlated with sediment characteristics, the highest numbers being recorded in sediments with large contents of organic carbon, silt and clay. Cyst assemblages were dominated by cysts of potentially toxic species, including Cochlodinium polykrikos, Prorocentrum minimum, Dinophysis acuminata, Alexandrium catenella and Scrippsiella trochoidea. Most cysts germinated successfully at different rates at 15 and 25◦C. This study suggests that surface sediments from all Saudi Red Sea coasts should be monitored for the presence of dinoflagellate cysts to give ample warning of the presence and abundance of toxic species in a given area.
