Grey Cement

 

Portland limestone cement NL 53: 1999 - PA-L 42.5 in bags

Composition

This product is manufactured by grinding a blend of clinker, selected limestone and calcium sulfate as setting regulator. Limestone content is between 6% and 15%.

Specific characteristics

This cement is a general use cement specially designed for standard building works. Limestone addition provides an excellent workability to mortar and concrete that make easier masons work.

Fields of application

This cement is ideal for site-mixed concrete, masonry, mortars, renders, grouts and small-scale concrete blocks production units.

Blast furnace composite cement NL 53:1999 - C-S 42.5 ChB in bulk

Composition

This cement is manufactured by grinding a blend of clinker, granulated blast furnace slag and calcium sulfate as setting regulator. Granulated blast furnace slag content is between 36% and 65%.

Specific characteristics

Cement C-S 42.5 ChB has low heat of hydration and is ground to a relatively high fineness. The addition of blast furnace slag reduces the permeability of concrete, limits the risk of salt efflorescence and improves the resistance of concrete to aggressive environments.  

Fields of application

The main fields of application of this cement are mass concrete like footings and raft foundations and normal quality ready mixed concrete, especially in summer time.
