Fine-grained reservoir sediments: an interesting alternative raw material for Portland cement clinker production
The paper reports investigation results on the use of fine sediments to replace a part of the raw materials in Portland cement (PC) clinker. Representative samples of sediments from three different French dam reservoirs are studied. These materials have a mineral composition that includes some of oxides components essential to cement manufacturing, such as SiO2, CaO, Al2O3 and Fe2O3. Their potential for use as replacement of clays in cement industry was considered. Nine mixes of PC clinkers were synthesised with feedstock mixtures containing between 20.6 and 31.1% of sediments according to their chemical composition. In all cases studied, usual clay materials are completely substituted by dam sediments. Clinkers were characterised using ICP-AES, XRD and optical microscopy. Results showed that synthesised clinkers have similar chemical and mineralogical composition than ordinary PC clinker. Finally fine-grained sediments might be considered as natural resource, they are an interesting alternative raw material for PC clinker production.
