✦ Synopsis

An investigation of the hydration behaviour of ordinary Portland cement clinker in the presence of coal, coke, and charcoal has been carried out. The physico-chemical characteristics of cement are greatly influenced by these materials. The water requirement 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 strength depends upon the nature of the materials. The hydration characteristics of different cementitious compositions have been investigated

with the help of infrared spectroscopy, X-ray diffraction and SEM analysis.

Crystallization of a liquid similar to that present in Portland cement at clinkering temperatures has been studied. Its composition (in wt %) is CaO = 54.8, A~203 = 22.7, Fez03 = 16.5, Si02 = 6.0. Prolonged crystallization or slow cooling yields the equilibrium phases: C3A, ferrite close to C,AF, an

In the system C3A-C~AF-SiO2-MgO, the glass formation region that is closely similar in composition to the interstitial material of portland cement clinker has been determined. The interstitial melt that exists in equilibrium with the silicates at the clinkering temperature contains a little silica.
