Talk | Material Matters: Use of Lime in Historic BuildingsDate: 9 April 2018Time: 5pmVenue: The URA Centre, Function Hall, Level 5
The origin of the word ‘lime’ is from Old English lim meaning ‘sticky substance.’ Lime was used as a binder for most historic buildings in most part of the world. It is a vapour permeable material that let the traditional buildings to breathe. Lime reduces the risk of trapped moisture and consequent damage to the building fabric. For this reason, it is essential to use lime to repair and maintain old buildings to match or copy qualities of the surviving original materials closely. It is necessary for anyone working on historic buildings to be thoroughly familiar with different forms of lime (lime mortars, plasters, lime-wash, etc.) as it is vital for the conservation of historic buildings.
Singapore's rich and varied heritage consists of many National Monuments, Conserved Buildings and marked historic sites. These sites are located island-wide and serve as tangible reminders of the nation’s shared heritage. For them to remain meaningful and useful for the study to the future generations, the present generation must take care of them in a way that they tell past stories through their various layers of building fabric. Any repair or change done to a historic building should be done in an ‘honest' way and by using compatible traditional building materials and techniques.
In this lecture, the speaker, Nikhil Joshi will highlight the need for old buildings to ‘breathe' and explain the different forms of lime and their principal characteristics and uses. This lecture will appeal to architects, students of architecture, surveyors, planners, conservators, and practising craftsmen in various fields, who wish to gain introductory knowledge about building limes.
Following this lecture, there will be a 4-day workshop at the NUS Baba House in which participants will enjoy practical hands-on sessions covering traditional techniques to use lime in historic buildings.
Dr Nikhil Joshi is Postdoctoral Fellow with Department of Architecture, NUS with research and practice in historic buildings conservation and community development. Besides conducting research and producing lime products at NUS-TTCL Centre for Asian Architectural and Urban Heritage in Melaka (Malaysia), Dr Joshi has provided consultancy to organizations in Australia, Malaysia, and India. In 2016, he successfully conducted lime-plastering workshop in Singapore.
Prior to joining NUS, Dr Joshi worked and taught in India, UK and Malaysia for over a decade. He is the only Indian till date to be awarded the prestigious Society for the Protection of Ancient Buildings – Lethaby Scholarship in 2007 by the oldest amenity society in the United Kingdom.
