Performance of dredged sediments based controlled low-strength material

Dredged Material Disposal Economics

Recent difficulties in siting dredged material disposal facilities are increasing interests in alternative disposal or reuse of dredged material and the possible adverse consequences of any increases in the generation of dredged materials. This paper focuses on economic aspects of these issues. Simple methods are suggested for evaluating the economics of increasing or decreasing the rate of dis...

Performance appraisal of industrial waste incineration bottom ash as controlled low-strength material.

Controlled low-strength material (CLSM) is slurry made by mixing sand, cement, ash, and water. It is primarily used as a replacement for soil and structural fillings. This paper presents the findings of a preliminary investigation carried out on the performance of industrial waste incineration bottom ash as CLSM. CLSM mixes were designed using industrial waste incineration bottom ash, and cemen...

Feasibility of decontaminating dredged material

Monitoring of Descending Dredged Material Plumes

Monitoring of 2 disposal operations on Lake Erie near Ashtabula, Ohio, provided an opportunity to employ different approaches to study the physical impact of the disposal of dredged material on the hydraulic regime of the lake in this area. A study conducted in August 1975 involved utilization of several transmissometers placed on 4 anchored vessels and one moving vessel. The transmissometers w...

Effect of Cement-fly Ash Additive on Compaction and Strength of Reservoir Dredged Material

Tremendous quantities of reservoir deposited sediments are required to be dredged regularly to maintain the storage capacity of the reservoir. The reservoir dredged material (RDM) can be utilized as construction material after admixing with additives such as cement and fly ash thereby improving its strength characteristics. This research paper presents results of laboratory investigation carrie...
