Practical Building Conservation: Concrete

£ 90.00

Despite some public antipathy towards its appearance and concerns about its longevity and environmental impact the importance of concrete to the nation's architectural heritage is gradually being acknowledged. Many concrete buildings have now been listed from farmbuildings sculptures houses and churches to large structures such as factories bridges and even whole housing estates. A number of buildings have been conserved to wide acclaimand this is helping to temper the perceived 'ugliness' of concrete as well as successfully extending the lifespan of the buildings themselves.The vast majority of iconic 20th-century structures have used concrete in some part of their construction even if this may not be readily visible. Many concrete structures have been built to a very high standard; others (for reasons of economy lack of knowledge expediency and poor workmanship or supervision) have been less well constructed but are nonetheless of architectural or historic importance and so may require conservation.The maintenance of this built infrastructure is socially important and given that premature demolition and new construction are neither economically or environmentally sustainable its conservation also has considerable environmental benefits. This volume considers how historically significant concrete buildings should be treated both in terms of preservation and repair. The interaction of the composite materials that make up concrete provides additional complexities that do not exist in homogenous materials. Furthermore the approach to conservation both in material and aesthetic terms may be different to that adopted for more traditional historic materials such as stone timber and plaster. For those materials retention of a certain amount of surface decay and weathering is acceptable and perhaps desirable but on a more modern concrete building technical issues and design intent may preclude this even though patina can play an important part in its appearance. One of the problems with conserving this complex material is that as yet the number of concrete conservation projects is small and there has been little opportunity for long-term monitoring of the results. Materials and methods will continue to evolve  through improvements in understanding and technology and as monitoring of treatments reveals more about good and bad practice.The book begins with a history of the use and development of concrete as a building material. The second chapter Deterioration & Damage looks at the ways in which concrete degrades or breaks down and the third covers the Assessment of concrete buildings as a prelude for determining approaches to their conservation. Treatment & Repair describes the range of methods that can be used to deal with the causes and consequences of deterioration and damage. This is followed by a chapter of Case Studies where specific examples are used to illustrate some of these general principles of repair. The final chapter Care & Maintenance gives guidance on how to maximise the preservation of concrete buildings whilst minimising long-termcosts.Published: March 2013Extent: 320 pagesBinding: Hardback
