Hydration of Portland cement clinker in the presence of carbonaceous materials
An investigation of the hydration behaviour of ordinary Portland cement clinker in the presence of coal, coke and charcoal has been carried out. The physio-chemical characteristics of cement are greatly influenced by these materials and setting times are increased. The 1-28 day compressive strength of the mortars are invariably lowered by the carbonaceous materials but the 90 day strenght depends upon the nature of the materials. IR spectrocopic study suggests that hydrated producs of compositions caontaining carbonaceous materials in general are richer in Ca(OH)2 than that of the clinker. SEM micrographs of 90 days cured pastes show presence of irregular and larger voids in compositions containing carbonaceous materials compared to those made with the clinker aline. For preparation of self-reducing iron ore pellets which require larger quantity of carbonaceous reductant, further investigations are necessary.
