Concrete admixtures for enhanced performance

Colorado River Bridge precast concrete structure produced with Sika admixtures

Concrete Admixtures are added to a concrete mixture in a very small amount, mainly to improve the performance of concrete in its solid and/or fresh state. Their purpose is to make concrete and construction works more durable and workable, by improving the water tightness (improving corrosion resistance, sulphate resistance, etc.) and by prolonging workability time and improving high early strength development, for example.

Sustainability is a very important aspect for this business area,? since for the cement and concrete industry aspects such as energy and resource efficiency, climate change, water scarcity and the rising need for efficient infrastructure are increasingly relevant. Sika’s Concrete Admixtures can support the construction industry, not only by influencing the performance but also, for example, by reducing water and cement consumption.
