Portland cement
EnduraShield Cement 42.5 N-LH/SR5
CEM I/42.5 N-LH/SR5 Cement - NA 442/2013 is a Portland Cement for concrete works requiring low heat of hydration.
Use of product
- Base cement for civil engineering works in aggressive environments.
- Concrete works requiring low heat of hydration and better durability.
- Maritime and hydraulic works.
- Desalination and treatment plants.
- Dams.
Product advantages
- Convenience when working with concrete / solutions mixture at the expense of high adhesion and uniformity
- Improved, convenient lay-out, and maintenance of features over time
- Efficient distribution of concrete mixture on the whole range of the pattern
- High adhesion with surfaces while carrying out plastering works, at even low temperatures at the expense of dynamics of quick hardening
- Reduced timing of construction works due to quick hardening of concrete
- Ability of easy distribution of concrete mixture on the whole range of the pattern.
- The high quality of texture of concrete items
- It does not require extra effort to level the surfaces
- ecologically pure cement
Health and safety
The chemical composition of the cement is in full compliance with sanitary epidemiological regimen in terms of harmful substances requiring the quality of the given building material.
