PIANO Betonverzögerer

Our concrete retarder based on natural L + tartaric acid can slow the setting of concrete, for example, if you do not want to get stressed in summer temperatures. Even a small dose of 1 to 5 grams per kg of concrete is enough in order to achieve a considerable retardant effect. The powdery product dissolves very easily during mixing. Apart from concrete, it is very suitable for retarding gypsum plasters.
