Cone Penetration In Cemented Deposits-A Field Study, Semih Arslan
LSU Historical Dissertations and Theses
Neglecting cementation results in an underestimation of slope stability and pile capacity in design and analysis of geotechnical engineering problems related to cemented deposits. Developing methods to identify and assess the engineering characteristics of cemented deposits is an important subject in geotechnical engineering.
This study is conducted to evaluate the reliability of the prediction schemes proposed by previous investigators through a field study of cone penetration in a cemented deposit and respective laboratory triaxial study on undisturbed cemented specimens. The effect of cementation on cone penetration resistance is investigated through the field study, and the effects of cementation on drained …

The theoretical hydraulic retention time of wastewater treatment plants is often used to predict the efficiency of treatment and to calculate operational parameters. However, these values are related to the actual hydraulic retention time. When there is a large discrepancy between the actual and predicted values, the actual hydraulic retention time can be determined by marking a parcel of wastewater and recording its passage through the system. This investigation utilized rhodamine WT, a fluorescent dye, to track the movement of wastewater through a stabilization lagoon and a rock-reed filter. The loss of rhodamine WT to sorption, biodegradation and photodegradation was …
