Static penetration test for historical masonry mortar

Construction and Building Materials, 2016
The penetration test for historical masonry mortar presented in this study is based on the principle of "static" penetration. A pin is driven at constant velocity by a stepper motor controlled by a computer. The test result is the penetration load as a function of the penetration depth.

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.

Radiocarbon Dating of Mortars and Charcoals from Novae Bath Complex: Sequential Dissolution of Historical and Experimental Mortar Samples with Pozzolanic Admixture

Radiocarbon: An International Journal of Cosmogenic Isotope Research, 2020
Carbonaceous mortars from Novae (Bulgaria) contain local loess, crushed bricks and ceramic dust (pozzolanic materials). The reaction between lime and pozzolanic additives occurs easily and affects the rate and course of leaching reaction of carbonates in

Hot-mixed lime mortar: historical and analytical evidence of its use in medieval wall painting plaster

, 2020
This paper presents evidence supported by scientific analyses and historical documents that medieval plasters used for wall paintings in Denmark were, with high probability, produced by mixing quicklime, aggregate and water in an exothermic process ...

Biodeterioration of mortar coating in historical buildings: Microclimatic characterization, material, and fungal community

Building and Environment, 2019
The estimation of climate conditions and different moisture sources associated with the substrate composition and features in historical buildings is crucial to evaluate the substrate biodeterioration by filamentous fungi.
