Canada’s historic buildings span the period where a dramatic evolution in building technology and material characteristics occurred. Evidence of the use of lime as the principle binder in mortars and plasters can be dated to the 6th millennium BC and it only fell from use in the beginning of the 20th Century following the introduction of early forms of cements, the predecessors of what we know today as Portland Cement. The workshop covers the full range of mortar materials and thinking, including the Lime Revival of the past 45 years.
- Mortar chronology, including hydraulic limes, natural cements, Portland cement and the historical and modern use of additives to enhance performance.
- The characteristics and performance of mortars
