RILEM TC 203-RHM: Repair mortars for historic masonry

Materials and Structures, 2012
This paper gives a summary of functional and performance requirements for repointing mortars for historic masonry (design, execution and maintenance). Successful performance of repair and conservation of mortar in historic masonry requires more care with design and execution than with modern masonry.

Mechanical Properties of Reproduced Historic Mosaic Mortar

Solid State Phenomena, 2021
Mortars containing linseed oil as admixture to lime were identified in several mosaics found in Czech Republic. These mosaics were made around 1900 and the composition of their bedding mortar was likely influenced by publication La Mosaïque by E. Gerspach [1], published in Paris, 1880.

Chemical Techniques of Historic Mortar Analysis

Bulletin of the Association for Preservation Technology, 1982
Summary Eight mortar standards of known composition were prepared and used to test the accuracy and applicability of three chemical techniques widely used to analyze historic mortars. The results indicated that only one of these techniques can be considered reliable when used to examine a broad range of historic mortars.

Gypsum Mortar in Historic Structures

The Masonry Society Journal, 1998
Gypsum has been used as a mortar since the time of the Pyramids. It has several advantages over traditional lime including lower fuel requirements for manufacture, greater strength, and more rapid setting time. Its major disadvantage is its relatively high solubility compared to lime mortar.

Nano-CaCO3 for Repair of Historic Joint Mortar

Iranian Journal of Science and Technology, Transactions of Civil Engineering, 2021
Joint mortars are one of the main components in the historic building. Mortar, similar to bricks, is usually subjected to deterioration caused by surrounding environmental conditions. Therefore, the current study focuses on the repair of the mortars using nano-calcium carbonate particles. The nano-particles were prepared by mechanical milling and mixed

Microscopy of historic mortars—a review

Cement and Concrete Research, 2006
Abstract Mortars with mud, gypsum and lime as binder have, since ancient times, been used for very different applications. The characterisation of these historic mortars was until 1970–1980 mostly based on traditional wet chemical analyses but the interpretation of these results is difficult and often impossible without a good knowledge of the nature
