The workshop will be of interest to those specifying or working with mortars for the repair of buildings. It will benefit the architect / mason making the transition into working on heritage structures and serve as an update for those already working in conservation but who may not have used Hot-mixes and earth mortars. It will also be a forum for those wishing to share their understanding of pozzolans and other aids to carbonation and how to test in the field.

Participants should go away knowing:

• how to interpret an existing mortar

• how to specify a good repair mortar

• the importance of understanding the materials

• how pozzolans enhance hydraulic set

• how to carry out field tests on their projects
