Nano-CaCO3 for Repair of Historic Joint Mortar
Iranian Journal of Science and Technology, Transactions of Civil Engineering, 2021Joint 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, 2006Abstract 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

Simple Analysis of Historical Lime Mortars
Journal of Chemical Education, 2014A laboratory experiment is described in which a simple characterization of a historical lime mortar is made by the determination of its approximate composition by a gravimetric method. Fourier transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD) are also used for the qualitative characterization of the lime mortar components.

Characterization of historic lime mortars
2006Historic lime mortars are an amalgam of natural and man-made materials. Thus, the study of lime mortars inherently requires interdisciplinary approaches. In an effort to evaluate the applicability of select analytical techniques typically utilized by geoscientists, fourteen samples of historic lime mortars are examined with transmitted polarized light ...

Investigation of the technology of historic mortars
Journal of Cultural Heritage, 2000Abstract Historical evidence on the use of mortars to meet several needs has existed for millennia. With reference to the characteristic historical periods of the city of Rhodes, mortar sampling was performed on historical constructions, masonry and architectural surfaces.

Historic Documents in Understanding and Evaluation of Historic Lime Mortars
2012Sophisticated analysing proceedings have been used in the past to assess the composition of hardened mortars. Chemical and mechanical tests combined with microscopic investigations seem to provide all the information required for the design of repair mortars which physically and visually are appropriate for restoration purposes. Lime putty and hydrated

Guidelines and Standards for Testing Historic Mortars
1996The restoration, rehabilitation, and adaptive reuse of existing structures increasingly are dominating the construction industry. The Secretary of the Interior's Standards for Rehabilitation of Historic Buildings and many local historic preservation codes require that when exterior restoration work is being planned, original pointing and construction ...

Hydraulicity in Historic Lime Mortars: A Review
2012Natural hydraulic limes were used in ancient times and are still produced today. A comparison of the chemistry and mineralogy of currently available NHL2 and NHL5 limes indicate that there are no clear differences except for the amount of ‘undefined material’, mainly comprising an amorphous phase.
