All Right Reserved.One of the problems to affect Portland cement matrices is low resistance to aggressive agents, due principally to the presence of a high content of portlandite in the hydrated cements. Pozzolanic materials have, for decades, played an important role in improving the durability of cement-based materials. This work studies the behaviour of cement mortar matrices blended with 10% calcined paper sludge (source for metakaolin, MK) and exposed to different environmental conditions (marine and tableland environments). The results obtained using X-ray diffraction and scanning electron microscopy/energy-dispersive X-ray analyser techniques show that the ions present speed of different penetration as well as various phases and/compounds in the matrices following exposure over 1 year.14enginfo:eu-repo/semantics/restrictedAccessjournal article10.1007/s11270-009-9990-2Calcined paper sludgeMarine environmentPozzolanic materialTableland environmentEnvironmental EngineeringEnvironmental ChemistryEcological ModelingWater Science and TechnologyPollutionhttp://www.scopus.com/inward/record.url?scp=85014456098&partnerID=8YFLogxK
