Delivery device
A delivery device for concrete admixtures, in the form of a film of watersoluble material, having a concrete admixture incorporated within the film. The film can be attached to a formwork for concrete and has a protective layer, which is removable to allow the water in the concrete to dissolve the film and release the admixture into the concrete. The film contains the required quantity of admixture and is weather-resistant and substantially time-insensitive. The delivery device is used in a process to retard the setting portion of a surface of concrete.
