Behaviour of polypropylene fibre mortars conserved in different environments

European Journal of Environmental and Civil Engineering, 2013
This paper presents the results of an experimental investigation to study the physical and mechanical performances of mortars reinforced by polypropylene fibres and stored for 91 days in three different environments (hot-dry, laboratory and cold environment).

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

Characterisation of Historic Mortars for Conservation Diagnosis

2018
Currently, several techniques are available for characterisation of mortar binders for research and conservation purposes but not all of them are suitable and affordable for routine diagnostic purposes. Cost efficiency is a very important factor for the scientific and conservation community and is always taken into account when designing a research ...

Air lime mortars for conservation of historic tiles: Bond strength of new mortars to old tiles

Construction and Building Materials, 2017
Abstract The present work studies the bond strength between new mortars and old tiles. The influence in tile/mortar bond strength of moisture content of tiles, mortars aggregates grain size distribution and nature, binder/aggregate ratio, different tile ceramic parts, water absorption and porous characteristics of historic tiles and new mortars were ...

Lime mortar and the conservation of historic structures

Australian Journal of Multi-Disciplinary Engineering, 2005
Lime and the lime mortars and plasters made from it have a long and successful history in building construction. However, the development of Portland cement in the 19th century gradually displaced or supplemented lime and much of the ancient trades knowledge has been lost, often to the detriment of masonry construction and conservation. The author has

Magnesian and Dolomitic Lime Mortars in Building Conservation

Journal of Architectural Conservation, 2000
AbstractMagnesian limes have only had a limited, regional application in traditional building work in the United Kingdom. Their properties are sufficiently different from those of high-calcium limes that structural problems may arise if they are produced using the same small-scale burning and slaking processes. Their use in building conservation should

Setting process of lime-based conservation mortars with barium hydroxide

Cement and Concrete Research, 2007
This paper presents the effect of barium hydroxide on the setting mechanism of lime-based conservation mortars, when used as an additive material. The study focuses on the monitoring of the setting process and the identification of the mineral phases formed, which are essential for furthering the study of the durability of barium mixtures against ...

Traditional hot mixed lime mortars for conservation and repair

Journal of Building Survey, Appraisal & Valuation, 2019
Earth-lime and hot mixed lime mortars were the almost ubiquitous materials of traditional construction over many thousands of years but have been sorely neglected, if not ignored, by a building conservation community philosophically wedded to the principle of like-for-like and compatible repair in favour of materials with minimal historic precedent for

Compatible Mortars for the Sustainable Conservation of Stone in Masonries

2018
Incompatible restoration mortars used extensively in recent years have inferred irreversible damage to the original building stones of masonries. Recent research has led to the development of compatibility criteria for the restoration mortars in relation to historical materials, through the reverse engineering approach. In the restoration of historical
