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.
20,000
metric tons of Sika concrete admixtures were used in the record-breaking Gotthard base tunnel project.
Thanks to Sika’s range of water-reducers for concrete, more than
6 billion
liters of water are saved annually in concrete production.
In the Lakhta Tower in Russia,
20,000 m³
of ready-mixed concrete with Sika admixtures were poured in one continuous operation, setting a Guinness World Record.
