Investigation of methods for removing stains from mortar and concrete
Investigation consisted of three parts -- evaluation of methods of removing stains from mortar and from concrete specimens; literature search indicated that types of troublesome stains are caused by iron, used lubricating oils, and cutback asphalts; several chemical and mechanical methods for their removal are outlined; mortar specimens were made in laboratory and stained to mild or severe degree with solution of iron chloride and lubricating oil; most effective removal techniques for iron stains were sandblasting, application of oxalic acid solution, and application of sodium citrate-sodium hydrosulfite paste.
