Lime mortar with natural pozzolana

2008
The paper deals with the investigation of the mechanical behavior of lime mortar enriched with natural pozzolana, widely used in historical masonry. The study aims to investigate the mechanical behavior of natural pozzolana lime mortars, reproduced in laboratory by using different mix designs, as reported in historical Italian architectural treatises ...

Hydromagnesite development in magnesian lime mortars

Materials Science and Engineering: A, 1999
Abstract The bond which develops during curing in lime paste mortars in the presence of Mg(OH)2 or MgO and moisture in lime paste is a result of the growth of a new phase. Scanning electron microscopy studies along with X-ray analyses show this new phase to consist of common hydromagnesite (Mg5(CO3)4(OH)2,4H2O).

LIME MORTARS WITH NATURAL FIBRES

2003
ABSTRACT Paper presents selected results of recent investigations [1] into behaviour of lime mortars modified with natural fibres or fibrous particles. It summarizes technical data of fibre reinforced mixtures made of lime matrix, sand and natural fibres (goat's and horses' hair) or fibrous particles (saw dust, husk), polypropylene fibres and sand ...

Succeeding with Hydraulic Lime Mortars

Journal of Architectural Conservation, 2002
AbstractThe paper describes what natural hydraulic limes are, how they relate to hydrated lime or Portland cement, and the role of pozzolanic materials when used in conjunction with them. The applications for natural hydraulic limes, including their benefits in terms of flexibility and permeability and their limitations in terms of speed of strength ...

Hot-Lime Mortars: A Current Perspective

Journal of Architectural Conservation, 2004
AbstractAnalytical and documentary evidence indicates that hot-lime mortars were used in traditional construction. These are defined as mortars manufactured by mixing quicklime and sand, rather than the current and more commonly adopted method of combining previously slaked lime with sand. Hot-lime mortars are again being used and are perceived to have

Characterization of historic lime mortars

2006
Historic 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 ...

Simple Analysis of Historical Lime Mortars

Journal of Chemical Education, 2014
A 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.

Portland Cement-Lime Mortars for Conservation

2018
It is currently widely accepted that lime, rather than Portland cement (PC), should be used for the repair of historic fabrics as most historic mortars were lime based and properties of PC mortar such as strength, stiffness and permeability can be incompatible with historic stone and brick, with consequent damage to fabrics. As a result, PC mortars are
