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 …
