How much cement is added?
The amount of cement added varies typically from a range of 5% to 30%. There is no “cookbook” recipe. Quantity of cement to be added is determined through a treatability study and mix design conducted on the individual subject waste or medium. Treatability studies can be simple or more involved depending on the project requirements. A description of an involved treatability study written by the U.S. Army Corps of Engineers is found at: http://www.usace.army.mil/publications/eng-tech-ltrs/etl1110-1-158/entire.pdf. Project managers may wish to review the description against project requirements, selecting elements of the described treatability study guide relevant to the project.
