This 2nd edition of the Code of Practice "Storing and Metering Concrete and Mortar Admixtures" was prepared by a project group appointed by Deutsche Bauchemie 's Special Committee 2 "Concrete Technology" and subsequently discussed and adopted by Special Committee 2. Its purpose is to provide information to users and other specialists in the trade on storing and metering concrete and mortar admixtures.
Practically all liquid concrete admixtures (BZM) are organic products and like food, they can spoil if not stored properly. Preservatives are also added to concrete admixtures just like they are to many foods. However, to protect the environment, there limits concerning the preservatives that can be added. Hygiene therefore plays an essential role when storing and metering concrete admixtures. This Code of Practice deals with these subjects in particular.
