Sika develops and markets a complete range of admixtures and additives for use in concrete, cement, and mortar production. These products enhance specific properties of the fresh or hardened concrete, such as workability, watertightness, durability, load-bearing capacity, or early and final strength. The demand for admixtures and additives
is currently on the rise, particularly due to the increased performance requirements placed on concrete and mortar, especially in urban areas and for infrastructure construction. Furthermore, the increasing use of alternative cementitious materials in cement, mortar, and therefore also in concrete, leads to a growth in the need for admixtures.

3D Concrete Printing

3D concrete printing (3DCP) is an advanced digital construction method that uses layer-by-layer deposition of cementitious materials to create buildings, structural elements and customised components without traditional formwork. This technology enables complex geometries, faster build times and greater design freedom. Sika provides specialised concrete admixture technologies developed for 3D printing, helping ensure rapid material extrusion, high precision and reliable performance throughout the printing process.

Sustainable Concrete Production

Workers on construction site pouring concrete onto slab on grade

Concrete is one of the world’s most widely used building materials. It is affordable, locally sourced, strong when combined with steel and highly durable - especially when enhanced with Sika products. However, concrete also has a notable environmental impact. It is the second most used substance on earth after water and it requires significant natural resources. Its key ingredient, cement, is responsible for around 8% of global CO₂ emissions and has an energy-intensive production process.

FAQ

What are concrete admixtures, and why are they used?

Concrete admixtures are special additives mixed into concrete to enhance its properties, such as workability, strength, durability and setting time. They help improve performance in extreme conditions, reduce water content and provide specific benefits like faster curing, reduced cracking and improved resistance to chemicals and freeze-thaw cycles.

What types of concrete admixtures does Sika offer?

Sika provides a comprehensive range of admixtures, including:

  • Water reducers and superplasticisers (for improved flow and reduced water content)
  • Accelerators and retarders (for controlling setting time)
  • Air-entraining agents (for freeze-thaw durability)
  • Corrosion inhibitors (for reinforced concrete protection)
  • Shrinkage reducers (for crack prevention)

How do superplasticisers improve concrete performance?

Superplasticisers significantly increase workability without adding extra water, allowing for stronger, more durable concrete with higher compressive strength. They also help in achieving high-performance, self-compacting and pumpable concrete mixtures.
