This European Standard applies to building lime used for:- preparation of binder for mortar (for example for masonry, rendering and plastering); - production of other construction products (for example calcium silicate bricks, autoclaved aerated concrete, concrete, etc.); - civil engineering applications (for example soil treatment, asphalt mixtures, etc.). It gives definitions for the different types of building lime and their classification. It also gives requirements for their chemical and physical properties which depend on the type of building lime and specifies the conformity criteria. Terms of delivery or other contractual conditions, normally included in documents exchanged between the supplier and the purchaser of building lime, are outside the scope of this European Standard.
