Limestone particle size distributions influence blended cement

Tuesday, 16 September 2014

Limestone cement with high packing density was developed to maximise binder properties in spite of increased limestone contents.

The replacement of an active material can improve cement paste performances.

The Israeli researchers used limestone powders with three main particle diameters relative to the clinker particles. They compared cements with a single-size limestone particle and with combinations of several particle sizes.

Combination of several particle sizes performed the best

It was concluded that the replacement of an active material with an inert additive can improve cement paste performances by increasing the surface area and the packing density of the cement-based particles, mainly when limestone powders with a combination of several different particle size distributions were used due to increased packing density.

The study is published in: Construction and Building Materials, Volume 71, 30 November 2014, Pages 26-34.
