Beschreibung
Because of concrete‘s great range of variety, it offers specifi ers and architects nearly unlimited possibilities. From simple structures to complex buildings of intricate design, practically all ideas can be realised with concrete. However, modern construction with concrete in all of its aspects would be unthinkable without concrete admixtures. Ever since statistics have been collected on the sale of concrete admixtures in Europe by EFCA, starting in the year 1994, the market has nearly tripled and has doubled in Germany since the beginning of the 1990s.
With the continuously growing ecological awareness that is spreading all over the world due to discussions on climate changes, construction materials have become a focus of general interest as important factors in assessing the sustainability of construction methods and buildings. The most used construction material in the world, concrete is of particular interest. A number of investigations and a great deal of research work in this fi eld are testimony. As a consequence, cement manufacturers are going to great efforts to optimise their carbon footprint when producing cement by reducing the quantity of clinker used in cement and thus also in concrete. In this connection, it is natural that concrete admixtures and their contribution to the sustainability of construction with concrete must be examined. A basis for this is Environmental Product Declarations. These have been available for a number of concrete admixtures for several years but must now be revised to follow the general development in this area.
