Economical heavy concrete weight coating for submarine pipelines

摘要

Economical heavy concrete weight coating is used as a weight coating for submarine pipes. The developed economical heavy concrete weight includes steel slag and iron ore as aggregate. Steel slag can contain iron and thus have a higher density than some other types of slag. By supplementing the steel slag with iron ore as aggregate, the economical heavy concrete weight coating can have a higher density than a coating having just slag. Economical heavy concrete weight coating can have a density greater than 190 pcf.
