Distinctive features of Portland cement

Advantages of modern Portland cement material

 Hardening strength: from 3 to 7 days, the process of increasing strength goes quickly, then the process slows down.

Subject to humidity in the room and a certain temperature, the strength continues to increase. 28 days are used to assess strength. Therefore, before the end of this period, finishing work on the surfaces finished with cement content is better not to perform.

 Frost resistance: depends on the presence of mineral additives in the production of cement, the subtlety of grinding and the ratio of water and cement. The more subtle grinding, the higher the frost resistance.

The presence of a large number of active mineral additives and an increased water -cement ratio negatively affects the frost resistance of cement.
