Cement for every application

Grey cement in bags.

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, which acts as a setting regulator. Limestone content is 6-15%.


Specific characteristics

This cement is a general-use cement specially designed for standard building works. The addition of limestone provides excellent workability to mortar and concrete, making masons' work easier.


Fields of application

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


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


Composition

This product has the same composition as the one available in bags.


Specific characteristics

This cement is a general-use cement especially designed for ready-mix concrete batching plants and precast concrete factories. Limestone addition provides excellent workability for concrete making, placement, pumping, and surface finishing. This cement can be used with a wide range of admixtures.


Fields of application

This cement is ideal for normal and high-quality ready-mixed concrete in non-aggressive environments, precast concrete, and manufactured concrete products. Its excellent workability makes this product especially suitable for fair-faced concrete.


Portland cement NL 53: 1999 – P 42.5 RMS BTNa in bulk


Composition

This product is a pure Portland cement. It is manufactured by grinding clinker and calcium sulfate as a setting regulator. The minimum clinker content is 90%.


Specific characteristics

This cement is relatively fast-hardening and gives high strength on a medium- and long-term basis. It has a moderate sulfate resistance and has low alkali. It can be used with a wide range of admixtures.


Fields of application

The main fields of application of this product are:

  • Works in a marine environment or in a moderately chemically aggressive environment
  • Limitation of alkali content of concrete
  • Medium to high strength reinforced and pre-stressed concrete, precast concrete

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 summertime.

White cement in bags.

White Portland cement in a bag


Composition

This product is manufactured by grinding a blend of white clinker, selected limestone, and calcium sulfate, which acts as a setting regulator. White clinker is produced by a specific process from selected raw materials with a very low content of metal oxides, particularly iron oxide.


Specific characteristics

The main characteristic of this product is its high whiteness index. Other characteristics are similar to those of Portland limestone cement. Limestone addition and high fineness provide excellent workability, which provides easier placement and surface finishing. White Portland cement mixed with limestone aggregates gives concrete and mortar a color close to natural limestone. The white Portland cement can be easily colored by addition of metal oxide pigments.


Fields of application

White mortar and white concrete have an infinite variety of shapes and surface finishes. 


The main applications are:

  • White bricklaying and plastering mortar
  • Repointing of stone masonry
  • Artificial stone

This product has the same composition as white cement in bags.


Specific characteristics

All the characteristics of white cement in bulk are similar to the ones mentioned above (in bags).


Fields of application

White mortar and white concrete provide an infinite variety of shapes and surface finishes. 


The main applications are:

  • Artificial stone
  • Precast street furniture
  • Fair-faced and architectural concrete
