The Influence of Limestone Additions on the Rheological Properties and Water Retention Value of Portland Cement Slurries


The recent changes on Brazilian specifications for Portland cement, in order to permit limestone additions, led to the necessity of knowing its influence in several aspects of the cement behavior when applied in civil construction.

In this paper the rheological properties, basically yield point and plastic viscosity, are determined in slurries made with cement which has up to 15% of limestone additions, in weight. For the same slurries the water retention value is obtained.

The variations in the yield point and plastic viscosity showed the “lubricity power” of the smaller particles (below 10 μm). Their amount is increased by the relatively greater grindability of the limestone concerning the clinker.

The limestone additions seem not to change the water retention value.
