cement clinker density

Portland cement clinker is a hydraulic material which shall consist of at least twothirds by mass of calcium silicates 2 and 2 the remainder consisting of aluminium and iron containing clinker phases and other ratio of CaO to SiO 2 shall not be less than 20 The magnesium oxide content MgO shall not exceed 50 by mass

density lower than portland conventional cement a mixture of ground cement clinker and gypsum The commonly assumed density of 3150 kgm 3 315 gcm 3 for portland cement 4 will not be correct when limestone is interground into the cement Neither ASTM C150 nor ASTM C595 requires the density to be reported or measured

The density of cement plays a significant role both in its production and performance The raw minerals are heated in huge ovens to promote chemical changes and this produces “clinker” The final steps in cement manufacturing involve grinding milling and blending that produce the fine powder that is recognizable as cement

The effect of cement composition on cement strength has been studied extensively 177182189400420 It appears that this effect is a rather complex one and depends on a variety of factors such as the mutual ratios of clinker minerals the amount and form of added calcium sulfate and the presence of minor oxides The available experimental data may be summarised as follows

What are the differences in these cement types and how are they tested produced and identified in practice In the most general sense portland cement is produced by heating sources of lime iron silica and alumina to clinkering temperature 2500 to 2800 degrees Fahrenheit in a rotating kiln then grinding the clinker to a fine powder
