Pioneering role in reducing clinker factor in cement
In recent years, our product portfolio has been undergoing
a successful switch to low CO2 cements, a
process which actively continued in the year under
review. Thus, in 2007, the proportion of consolidated
cement sales attributable to traditional Portland
cements fell to less than 30 percent, as against nearly
twice that figure in 1995.
Our extended product range not only enabled us to
improve our ecological profile in many markets, but
also allowed us to offer customers made-to-measure
application-specific solutions using composite
cements which are becoming increasingly important.
The focus of research and development activity is
on eco-efficient products and services. The main
emphasis is on system solutions based on a holistic
view of the entire process from the manufacture of
the product to its use and recycling. Projects were
launched which will ensure the Group’s leading role
in this area over the coming years.

Eco-efficient products with exceptional resistance
One example from the eco-efficient product range is
CEMROC®, a building material which offers a combination
of very low CO2 emissions in production and a
final concrete product that shows exceptional resistance
to attack by chemical agents and has exemplary
properties in terms of durability and service life.
The production of CEMROC® involves adding extra
components to a slag cement which give the endproduct
concrete enhanced properties and make it
resistant to aggressive environmental conditions.
A product based on a by-product of coal-fired power
plants which is comparable with CEMROC® in terms
of environmental impact and use is already at an
advanced stage of development.
