Discover the wide range of raw materials used both in the past and today to make mortars, plasters and renders for traditional Scottish structures.
Classification of raw materials and their impact on the physical properties of mortars is the core focus of this module. You will also examine the relevant British Standards for lime binders and aggregates, and why it’s best not to rely wholly on these in the specification of mortars.
Find out how mortar preparation is affected by water content and mixing time as well as by additives. The technical suitability of proprietary ‘restoration mortars’ and ready mixed materials will be discussed – as will the philosophical implications of their use.
This module has a significant practical element, letting you gain first-hand knowledge of how different mortars, plaster and renders should be worked. You will also try out methods of mortar analysis such as acid digestion, X-ray diffraction and petrographic analysis.
