Cement
Cement is manufactured through a large-scale, complex
and capital-intensive industrial process. At the core
of the production process is the rotary kiln, in which
limestone and clay are heated to around 1,450 degrees
Celsius and the semifinished product clinker is
created by sintering. In the cement mill, gypsum is
added to the clinker and the mixture is ground to
a fine powder – traditional Portland cement. Holcim
offers customers a wide range of cementitious
materials and also develops customized blends for
special applications. To produce these, other highgrade
materials such as granulated blast furnace
slag, fly ash, pozzolan and limestone are added in
order to modify the properties of the cement.

Aggregates
Aggregates include crushed stone, gravel and sand.
Production centers around quarrying, preparing and
sorting the raw material. Aggregates are mainly used
in the manufacture of ready-mix concrete, concrete
products and asphalt as well as for road building and
railway tracks. The recycling of aggregates from concrete
demolition material is gaining in importance at
Holcim.

Other construction materials and services
Globally, concrete is the second most consumed commodity
by volume after water. One cubic meter consists
of approximately 300 kilograms of cement, 150
liters of water and 2 tonnes of aggregates. Asphalt is
a bituminous construction material used primarily for
road paving. By weight, asphalt consists mainly of
aggregates of differing grain size. Essentially, Holcim’s
service also includes construction services and international
trading.
