Influence of the mechanical properties of lime mortar on the strength of brick masonry
(Springer New York, 2013)This paper aims at improving the quality of lime mortar masonry by understanding the mechanics of mortars and masonry and their interaction. It investigates how the mortar?s compressive and flexural strengths impact ... -
Influence of loading rate and specimen geometry on lime mortar strength
(2012)Compressive and flexural strength are important properties because they relate to the quality and durability of a material, and its suitability for a particular design or application. In addition, compressive strength is ... -
Impact of water retainers in the strength, drying and setting of lime hemp concrete
(2012)Lime hemp concrete is a sustainable, carbon negative building material that can be used in certain applications lowering the environmental impact of construction. Hemp absorbs large quantities of mixing water (325% of its ... -
Influence of the aggregate quality on the physical properties of natural feebly-hydraulic lime mortars.
(Springer, 2008)This paper examines the influence of the shape, average size and calcite content of the aggregate on strength, porosity, water absorption, density and capillary suction of natural feebly- hydraulic lime (NHL 2) mortars. ... -
A study of the workability of natural hydraulic lime mortars and its influence on strength
(Springer, 2008)Lime mortars are currently used for both repairs to historic buildings and new construction. An important mortar property is workability. Lime mortars are often described as highly workable, however, due to the many ... -
An overview of the University College Dublin hollow cylinder apparatus
(2001)Most sedimentary soils are inherently ansiotropic. Their response to loading will depend on the directions of the principal stresses. In most geotechnical problems the principal stresses gradually rotate during loading. ... -
Design approach for improving rampart roads
(2008)Approximately 17% of the land surface of Ireland is covered with peat. However, some counties have significantly higher values, particularly in the midlands and western counties. County Leitrim, for instance, has peat ... -
Geotechnical Research Trinity College Dublin
(2005)The Geotechnical Group of the Department of Civil, Structural and Environmental Engineering is actively researching solutions to some of the key issues that need to be addressed in the construction of civil engineering ... -
Case study of an interdisciplinary problem-based engineering design course
(2008)This paper describes an interdisciplinary problem-based engineering design course taken by about 170 students in the second year of the Bachelor of Engineering degree program at Trinity College Dublin. The course runs ... -
Irish Researchers Develop Automated Anisotropic Test Kit
(2003)A hollow cylinder apparatus for measuring anisotropic soil behaviour has been developed by researchers at the National University of Ireland, Dublin. Dr Brendan O'Kelly and Pat Naughton said the automated apparatus ... -
An investigation of Roman mortar technology through the petrographic analysis of archaeological material
(Elsevier, 2007)This paper studies Roman mortars to demonstrate that petrographic analysis provides valuable information on ancient mortar technology. Facts on lime technology relating calcination and slaking were obtained through ... -
Design of quality, durable mortar for the conservation of historic masonry fabrics
(Thomas Telford, London, 2005)The last twenty years have shown a steady increase in the number of conservation works to historic structures carried out in Ireland. Much of the repair and maintenance to historic masonry buildings have required pointing, ... -
The attenuation of microorganisms in on-site wastewater effluent discharged into highly permeable subsoils
(2012)An extensive field study on percolation areas receiving both septic tank and secondary treated on-site effluents from single houses in Ireland was carried out to investigate the attenuation capacity of highly permeable ... -
Numerical modelling of the passive control of air pollution in asymmetrical urban street canyons using refined mesh discretization schemes
(2012)This study evaluates the potential of passive controls in asymmetrical street canyons to reduce personal exposure to air pollutants on footpaths. A passive control in the form of a low boundary wall (LBW) may act as a ... -
Energy Monitoring Programme for Social Housing in Ireland: Pre- and Post- Retrofitting
(2012-01)There is a scarcity of empirical data to demonstrate the actual benefit of energy efficient retrofitting in the residential sector. The Irish official methodology for calculating the energy rating of dwellings only ... -
Environmental Tobacco Smoke in Designated Smoking Areas in the Hospitality Industry: Exposure Measurement, Exposure Modelling & Policy Assessment
(2012)Tobacco control policy has been enacted in many jurisdictions worldwide banning smoking in the workplace. In the hospitality sector many businesses such as bars, hotels and restaurants have installed designated smoking ... -
The inactivation of phages MS2, ΦX174 and PR 772 using UV and solar photocatalysis
(2012)The photolytic and photocatalytic disinfection of three bacteriophages (MS2, ?X174, PR772) under both artificial UV irradiation and natural sunlight was studied. A large variation was seen in the relative responses of ... -
Air-tightness field data for dwellings in Ireland
(Elsevier, 2012)Air-tightness plays a major role in both building energy performance and indoor environmental quality. Ireland's National Methodology for the calculation of energy performance of buildings, the Building Energy Rating (BER) ... -
The Characteristics and Properties of Rubbing Bricks used for Gauged Brickwork. Part II
(Donhead, 2003)This paper provides a continuation of `The Characteristics and Properties of Rubbing Bricks used for Gauged Brickwork ? Part One?, published by Gerard Lynch and Sara Pavia in the March 2003 issue of the Journal of ...
