Introduction to Lime Based Mortars for Civil and Structural Engineers CE1

Location: Charlestown Workshops, Fife KY11 3EN

About this event

This one day introductory workshop introduces the range of lime and early patented cement based mortars that have been used in the past for the construction of masonry arch bridges, culverts, tunnels, light houses, viaducts, canals, harbours, retaining walls, piers and other masonry structures which contribute so much to the richness of our built heritage. But in many cases, we are asking these structures to outperform any of the expectations that their original designers intended which can leave us with various ‘headaches’ to deal with, without spoiling their beautiful aesthetics. There are now a wide range of lime and natural cement binders and other additives (based on historic additives) that can be used to emulate both the technical and aesthetic performance of original mortars.

Course Suitability

This course is suitable for Structural & Civil Engineers and their technicians including those that look after our roads and railway network, contractors working on unprotected masonry structures and custodians of our industrial heritage.

Learning Outcomes

• Recognising common types of failures in masonry construction;
• Ability to recognise different types of mortar, what are original and what are later interventions;
• Understanding masonry unit construction in solid walls and the role of mortars;
• Identifying the mortar performance requirements of replacement mortars on different elements of a structure, including above and below high and low water marks, cut waters, piers, abutments, aprons and the like, bridge spandrels walls subject to heavy road traffic, parapets in general, retaining walls; embankments, undersides of arches, tunnel walls and the like;
• Use of additives to augment the working and final performance characteristics of replacement mortars;
• Design of appropriate mortars for repair, maintenance and conservation programmes of work;
• Making and using mortars with accuracy and consistency;
• Application and curing of mortars for repointing and rebuilding works.
