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.

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 superplasticizers (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 superplasticizers improve concrete performance?

Superplasticizers 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.

Can concrete admixtures improve sustainability in construction?

Yes, admixtures help reduce cement and water consumption, lower CO₂ emissions and enhance concrete durability, leading to longer service life and less maintenance. Sika’s innovative admixtures support eco-friendly construction practices by enabling the use of recycled aggregates and alternative cements.

How do I choose the right admixture for my project?

The right admixture depends on factors like project requirements, environmental conditions and performance goals. Sika’s technical experts can help recommend the best solution based on your specific needs, whether for high-strength concrete, waterproofing or durability enhancement.

Sprayed Concrete

Successful sprayed concrete requires the combination of many aspects of modern concrete technology especially concrete admixture chemistry, together with modern materials handling technology. The increasing demands for cost-effectiveness and the protection of health and the environment mean that sprayed concrete has been in continuous development. Thanks to more than one hundred years of experience, expert knowledge and a focus on performance and economy, Sika is able to provide the newest generation of sprayed concrete solutions.

Fibre Types

Different fibre types are used to deliver different performance requirements. Short, thin synthetic fibres are used for fire protection and crack reduction, whilst long synthetic or steel fibres generally come into play to increase energy absorption. One size doesn’t always fit all, and special requirements demand special fibre materials and shapes – Ultra High Performance Concrete (UHPC) requires short fibres with a high E-modulus, for example. Sika provides solutions for all these eventualities, as well as other special types and blends of fibres.

Improved Concrete Performance with Fibres

Specific concrete characteristics are obtained by using different fibre types, or mixtures of different fibres, depending on what the performance requirements are. Longer high E-modulus fibres are used to achieve high energy absorption, whilst longer low E-modulus fibres are used for increased ductility and crack reduction.

Watertight Concrete System

Waterproof concrete is an impermeable concrete used for long-lasting, durable watertight construction. To improve the impermeability of the concrete, water-resisting admixtures can be added. Nevertheless, design and construction of a watertight concrete structure is a system approach, and waterproof concrete is only one element of it. Water impermeability is determined by fulfilling requirements to limit water permeability through the concrete itself, the joints, installation parts and cracks.

Alkali-Silica-Reaction Resistant Concrete

Major infrastructure projects such as dams, roadways or airport runways require enormous quantities of aggregates, sought in closest proximity to construction sites. Some aggregates can exhibit an increased or high risk of ASR. Alkali-Silica-Reaction is a chemical reaction which occurs between the amorphous silica in the aggregate and the pore solution (alkalis) of the cement matrix.

Fire Resistant Concrete

The danger of fire is present always and everywhere. The imminent danger depends upon actual exposure, and naturally differs if the threatened construction is a pedestrian subway, a roadway tunnel or a subterranean garage in a skyscraper. Concrete is the loadbearing material in nearly all built structures and is therefore at high risk, since the entire structure would collapse upon its material failure.

Chemical Resistant Concrete

Water is the source of all life as well as a scarce commodity. Clean drinking water should therefore be protected against contamination, while waste water must be treated before being released into a discharge system. The waste water itself as well as the treatment measures undertaken represent an exposure to chemicals for concrete surfaces.

Abrasion Resistant Concrete

Awe-inspiring gorges and valleys are nature’s testimony to the undeniable strength of water. Primarily in technical hydraulic engineering, but also in traffic zones with high loads or hard rolling bodies, concrete surfaces experience considerable and at times extremely abrasive forces. The mechanisms of damage thereby depend centrally on the type of burden.

Sulfate Resistant Concrete

Particularly in underground construction, concrete structures are exposed alongside loads and wear of decade-long use to influences emerging from the sub grade such as permanent mechanical stresses and aggressive water.

Corrosion Resistant Concrete

Concrete is an ingenious building material, also because in combination with reinforcing steel it exhibits tremendous load-bearing capacity. The combination of steel and concrete has the advantage that under normal conditions the high pH value of concrete creates a passivating layer of iron hydroxides on the steel surface, which protects it from corrosion. Particularly steel, however, can be compromised in its durability of performance by the presence of moisture and salt.
