Portland cement is a product that is made by mixing, grinding and kilning raw materials of limestone, marl, clay, iron ore, pyrite ash, bauxite, etc., and grinding the resulting clinker with a certain amount of regulator (usually gypsum); which cures and gains strength after a certain period of time after mixing with the water.

This cement is manufactured by grinding of Portland cement clinker, settler (gypsum) and up to max. 5% minor supplementary components, in accordance with TS EN 197-1:2012 “Cement – Part 1: General Cement – Composition, Properties and conformity criteria” standard, to have a 2 day compressive strength of at least 20 MPa and a 28 day compressive strength of at least 52.5 MPa.

It is the result obtained by grinding mineral admixtures (pumice and limestone) and Portland cement clinker together with a certain amount of settling agent (gypsum) defined in the standards (up to 20%); which hardens and gains strength after mixing with water.

It is the result obtained by grinding mineral admixtures (pumice) and portland cement clinker together with a certain amount of settling agent (gypsum) defined in the standards (up to 55%); which hardens and gains strength after mixing with water.

For foundation, dam and construction infrastructure works where sulfate attack are more probable sulfate resisting pozzolanic cement usage is preferable.
