Chemical Composition and Heavy Metal Content of Portland Cement in Northern Tunisia

Résumé fourni par la source

This study aims to determine the major elements of Portland cement type I and II (CEMI and CEMII) in a cement factory in north Tunisia and which metal elements are introduced into the production process. We determine also the metal input rate and their distribution at the entrance and exit of the process. The major elements were analyzed and the trace elements (Arsenic, barium, lead, mercury, boron, strontium, Cadmium, Chromium, copper, manganese, nickel, and zinc) were identified. The concentrations of heavy metals in CEMI showed no significant difference p
