Accelerator & Retarder

The accelerator without chlorine Harmony Béton is a ready to use to incorporate during the preparation of concrete, into the router or the cement mixer. The making of concrete accelerator allows: an acceleration of taking screeds or formwork, thus reducing time of harvest or application of the selected finishes; an increase of mechanical resistance in the short term. Harmony Accélérateur Béton is the solution that allows the realization of your work in all weathers, all year round.
