Abstract

The use of blast furnace slag for the production of binders dates back to the second half of the XIX century. In 1853, Germany was the first country to perform the water-granulation of blast furnace slag, and in 1862, Emil Lange discovered its hydraulic properties. These two events should be considered the beginning of the use of granulated blast furnace slag (GBFS) as cement component, for in 1865 Germany launched the production of slag-calcium cements. This type of cement has been widely used in Europe at that time, among others, the construction of the Paris subway tunnels. The leading position in the production of this type of cement occupied Germany, which in 1888 launched the first slag cement grinding plants.
In the first half of the XX century cements with the addition of slag were more widely used in Western Europe and the United States. An example of this may be the Benelux countries, especially the Netherlands. The need for the construction of port facilities, locks and dams, resulted in the exploration of materials durable under the attack of seawater. The selection of slag cements proved to be very accurate, due to their high resistance to corrosion.
Currently, the development of slag content cement in Europe and around the world is very intense. Environmental policy favors the situation, especially the European Union (reducing greenhouse gas emissions, mainly CO₂), which became the inspiration to explore new technological solutions to reduce energy consumption and non-renewable resources in the production of cement.
New developments in the cement industry, scientific research and the practical realization of sustainable buildings lead to the conclusion that cements containing GBFS and other additives are a fully valued binders for the construction industry, which largely will shape the image of European cement industry in the future.
