Sika® Concrete Admixtures
One of the most important ingredients in high performance, long-lasting, durable and beautiful concrete produced today are concrete admixtures. Concrete admixtures are natural or manufactured chemicals or additives added during concrete mixing to enhance specific properties of the fresh or hardened concrete, such as workability, durability, or early and final strength.
Chemical admixtures are one of the components in high-performance concrete
The first step in optimizing concrete is to recognize that concrete is no longer simply cementitious materials, aggregates and water. It is a high performance material with not just four, but seven essentials – consisting of water, cementitious material, sand, gravel, chemical admixtures, additives and fiber reinforcement.

Admixtures for Improved Fresh Concrete Properties
Sika’s admixtures can improve fresh concrete workability properties like pumping or self-compacting, which enables concrete to flow easily through and into confined spaces.

Accelerating Admixtures
All participants in the construction process want to achieve sufficient early strength to allow formwork removal as quickly as possible, whether in shotcrete for construction sites or in concrete production.
