Concrete, the single most widely-used building material in the world, has a history dating back to the Romans and ancient Egyptians. Given that concrete is used twice as much in construction over all other building materials, emphasis on quality, performance and sustainability is essential for the industry to grow and thrive.

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.  

For over
100 years,
Sika has been producing high quality, innovative technologies for concrete, beginning with the first product named Sika®-1, which is still in the Sika product portfolio today.
metric tons of Sika concrete admixtures were used in the record-breaking Gotthard base tunnel project.
Every year,
more than 6 billion
liters of water are saved in concrete production, thanks to Sika’s range of water-reducers for concrete.
110 million
tons of cement are saved by using SikaGrind®. By replacing clinker in cement with alternative fines, we can make the biggest impact to reduce CO2 in the world's most important construction material.

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.

With this One Material – Concrete – Sika Supports in Your Project Needs

Our local sales and technical services teams support you throughout every phase of the construction process: from the initial consultation and project planning phase, to the detailed design phase and application on the job site and finally quality control, completion and final handover.

Ready-mix Concrete Producer

Engineering of concrete structures is a continuously evolving process. Invention and development of new construction methods place increasing demands on the building materials. Concrete producers face this technological challenge daily alongside other factors such as economy, ecology, raw material and energy costs and logistical complexity. In the duration of the whole construction process, time itself is an increasingly important factor.

Sika provides a wide range of concrete admixtures with innovative options for concrete mix design, whether it's for substantially reducing the water content of a mix (e.g. with Sika® ViscoCrete), using a more economical mix design or achieving sufficient early strength. Sika's concrete admixtures help you meet the challenges of modern concrete technology and the construction business.

Precast Concrete Industry

Structural design and construction with precast concrete elements require versatile products, from wet precast production to erection on site. Sika, a full range supplier, meets the diverse complexity of the entire precast concrete element production and construction process with solutions for all requirements, e.g. SikaRapid® for fast cycle times.

Find the right products for wet precast concrete.

  • Semi-Dry Precast Concrete

The semi-dry precast concrete industry manufactures large quantities of finished concrete products with high quality surface appearance and excellent durability. SikaPaver® products significantly improve both the manufacturing process as well as the quality of semi-dry precast concrete products. Furthermore, it is possible to reduce efflorescence or even incorporate water-repellent behavior by using SikaPaver® AE.
