Abstract

Purpose

The purpose of this paper is to address the issue of perceptions of suitability of different materials for a repair. The use of highly cementitious materials in the repair of historic masonry is causing great concern due to their incompatibility with adjacent stone and the associated accelerated deterioration which results from their use. The relatively recent development of so‐called “restoration mortars” based on a “mix and go” application, combined with the enhanced weathering of stone in a changing climate, may be contributing to the use of “plastic” repair materials on stone across Scotland.

Design/methodology/approach

Following a literature review, case studies of repairs are presented to highlight the advantages and disadvantages of using such materials, and comparisons are made with the alternative options.

Findings

The case studies presented highlight the use of a number of different stone repair materials, sometimes in combination with stone replacement, representing functional and philosophical approaches to masonry repair. However, the research has also highlighted the increasing use of plastic repairs for large‐scale repair including façade rendering, which fail to incorporate these systematic and informed approaches, and can ultimately lead to failure of repairs.

Originality/value

An evaluation of the current standing of the materials, methods and the extent of this type of repair, is vital for the substantiation of further research, and to enhance the empirical knowledge of in‐use performance, longevity and failure. The increasing emergence of restoration mortars, and their manufacture and supply on an international scale, highlights the global impact and relevance of this research.

Abstract

INTRODUCTION To choose 1958 as the year terminating a study of the development of public library facilities in Argyll may seem somewhat arbitrary. The year is chosen as marking the completion of the County Library system as conceived at its commencement in 1946. It was only then that the last of the Burgh Libraries became integrated into the service and it could be said to cover the whole county. Further developments took place within the context of this service but the concern of this paper is to examine the history which led up to its establishment. This is done mainly through the study of original material such as correspondence and reports. Since much of the available material related to the protracted period of negotiation between the County Authorities and the Carnegie United Kingdom Trust it seemed possible to concentrate on the activity of the Trust in the general development of rural library services in Scotland. During the years spent in considering their own position the Argyll authorities collected much information concerning other areas. Argyll's efforts, or the lack of them, might have been placed in comparison with activity elsewhere. However, it became obvious that services in other areas developed on individual lines which made comparisons possible only in the broadest of terms. Similarly, the Trust operated a policy within broad and negotiable guidelines involving detailed regulation on only a minimum of issues which were considered to be vital.
