BS 6319-12:1992

This standard BS 6319-12:1992 Testing of resin and polymer/cement compositions for use in construction is classified in these ICS categories:

• 91.100.10 Cement. Gypsum. Lime. Mortar

This Part of BS 6319 describes the methods for the measurement of linear shrinkage from initial gel and of the coefficient of thermal expansion of hardened polymer and polymer/cement mortars in the form of unrestrained thin strips (less than 20 mm in thickness).

The methods are suitable for materials that do not contain aggregates larger than 3 mm used in thin layers for patch repairs and surfacing applications.

Length changes of a layer of material are measured until set. The hardened specimen is then subjected to heating and cooling cycles.
