The Sika Contribution to Sustainable Construction

Concrete admixtures can improve the sustainability of concrete in many different ways. Firstly, admixtures can improve the quality and performance of concrete significantly, which in return extends its service life. In addition, thanks to the use of admixtures the application of concrete instead of other building materials can improve the life cycle of infrastructures, i.e. concrete roads greatly improve the quality and durability of highways for main traffic arteries compared with conventional road surfacing.
The LCA of Concrete Admixtures follows a "Cradle to Gate with option" approach, and its aim is to analyze the production of Concrete Admixtures and their application in concrete. The LCA model was reviewed by the leading independent research institute Swiss Federal Laboratories for Materials Science and Technology (EMPA).

Sustainability in concrete with Sika admixtures

Concrete admixtures can improve the sustainability of concrete in many different ways. Firstly, admixtures can improve the quality and performance of concrete significantly, which in return extends its service life.
In addition, thanks to the use of admixtures the application of concrete instead of other building materials can improve the life cycle of infrastructures, i.e. concrete roads or bridges.


Further, the addition of special admixtures, such as stabilizing or water reducing admixtures also enables the use of alternative and recycled materials, such as recycled aggregates, for the production of good quality concrete.
Finally, in many cases the energy required to produce certain cement or concrete mixes will be positively impacted with the use of admixtures. One example is the addition of water reducing and accelerating admixtures to obtain high early strengths in precast concrete to greatly reduced or even completely replaced external heating of elements.
