Concrete. Curring compounds. Specifications and test methods

Scope

This standard specifies the requirements for liquid membrane-forming materials which are applied on the surface of fresh concrete in order to reduce undesirable water evaporation at an early age, shortly called curring compounds.
In case that the protective compositions are white in color or possess reflective properties, they can also be used to reduce the temperature of the concrete when it is exposed to direct sun radiation.
The curing compounds shall have a numerous of special properties, such as alkali resistance, good adhesion to concrete and ultraviolet light resistance.
Issues related to safety in the use of the curing compounds are not listed in this standard. If any, they should be declared by the manufacturer of the compound concerned so that consumers can make an informed choice of compound and choose appropriate safety measures when use.
This standard is a specification regarding the properties of protective compositions.
This standard is a specification regarding the characteristics of the curing compounds. It has no relation to the proportions of the constituent materials, permissible content of various components etc., which may be the subject of other normative documents. It does not address issues such as air quality, workmanship exposure and other potential risks. Conformity with the requirements for health and safety at work is the responsibility of manufacturers and the users of curing compounds.
