This volume focuses on research and practical issues connected with mortars on historic
structures. The book is divided into four sections: Characterisation of Historic Mortars
Repair Mortars and Design Issues Experimental Research into Properties of Repair Mortars and
Assessment and Testing. The papers present the latest work of researchers in their field. The
individual contributions were selected from the contributions to the 2nd Historic Mortars
Conference which took place in Prague September 22-24 2010. All papers were reviewed and
improved as necessary before publication. This peer review process by the editors resulted in
the 34 individual contributions included in here. One extra paper reviewing and summarising
State-of-the-Art knowledge covered by this publication was added as a starting and navigational
point for the reader. The editors believe that having these papers in print is important and
they hope that it will stimulate further research into historic mortars and related subjects.
