Increase revenue

Many concrete producers have expressed concerns about the ability to economically access the highest quality aggregates. Some quarry reserves have high levels of expansive clay, which has made using these reserves a costly proposition.

CLARENA® AC additives help quarry owners extend the functional lifespan of their property. By mitigating the effects of clay, reserves that might otherwise be difficult and expensive to clean, can be safely used without reducing the performance of concrete. As an additive, CLARENA® AC products are easier to use and more effective than mechanical or equipment solutions.

Why CLARENA® AC additives?

Using CLARENA® AC additives give aggregate and ready mix producers the assurance that each batch of concrete will perform consistently, even if clay is present in the aggregates. This aggregate additive gives producers better control over their material, while ensuring that the use of the aggregate reserves is maximized.

Get a great-performing mix

For ready mix producers, CLARENA® AC products add controllability to concretes containing aggregates with a high clay content. They help produce a consistent concrete that exhibits excellent slump development and slump retention, along with reduced air entrainment variability. The superior finishing characteristics make the concrete suitable for commercial and residential flatwork and formed concrete.
