Presence of emerging contaminants in treated sludges and their potential impacts on the environment
(NUI Galway, 2018-11-13)
Landspreading of sewage sludge remains the most economical and practical means for its disposal, with some countries, such as Ireland, disposing up to 90% to land. Its nitrogen, phosphorus and metal content make it an ...
Stabilisation of a dredged marine sediment: geotechnical and contaminant leaching properties
(Civil Engineering Research in Ireland CERI, 2018-08-29)
In this paper, contaminated sediment dredged from a commercial harbour in Ireland was stabilized using Ordinary Portland cement (OPC) alone and in combination with Ground Granulated Blast Furnace Slag (GGBS). The engineering ...
Blackpool South Strategy project: analysis of pipe-jacking records
(Civil Engineering Research in Ireland CERI, 2018-08-29)
In recent years, there has been an increased resort to microtunnelling/pipe-jacking as a means of constructing underground conduits (for water, sewage, gas and other utilities) to avoid on-street disruption in urban areas. ...
Laboratory Push-In Resistance Tests (PIRT) in a cement-stabilised pseudo-fibrous peat
(Civil Engineering Research in Ireland CERI, 2018-08-29)
Deep dry soil mixing (DDSM) is a form of ground improvement in which dry binders are injected and mixed in
situ, forming individual columns, rows or interlocking panels, thereby improving the geotechnical characteristics ...
Evaluation of the structural behaviour of beam-beam connection systems using compressed wood dowels and plates
(NUI Galway, 2018-08-20)
To support the transition to a bio-based society, it is preferable to substitute metallic fasteners and adhesives in timber construction with an eco-friendly alternative. Recent studies have identified compressed wood ...
Numerical simulation and assessment of the effects of inlet configuration on the flushing time of a potable water service reservoir
(Conferences and Events at DigitalCommons@USU, 2018-05-15)
Service reservoirs provide the dual function of balancing supply with demand and providing adequate pressure in the water supply network by maintaining sufficient pressure head. In a potable water service reservoir, the ...
Experimental investigation of the serviceability behaviour of a cross laminated timber floor
(NUI Galway, 2018-08-29)
European timber design standards set out basic serviceability limit design criteria for single span, simply supported floors, but the rotational stiffness of the fixing system and two-way support possible with modern solid ...
Mechano-sorptive creep in reinforced glulam
(National University of Ireland Galway, 2018-08-20)
An investigation was carried out to examine the effect of reinforcement on the creep behaviour of FRP
reinforced timber elements in a controlled variable climate. Creep is accelerated by moisture variations due to a ...
Mechanical properties estimation by non-destructive testing of Irish hardwood round timber from thinnings for construction purposes
(Department of Forestry Policy and Economics, University of Sopron, Hungary, 2018-10-25)
Thinning involves the removal of competitors of high quality trees, and trees for extraction racks, all to favour the growth of the selected trees. Many felled trees are small-diameter and in Ireland hardwood thinnings are ...
Multiphase numerical modelling of hydraulic structures with rapidly rotating flows: Stormwater vortex hydrodynamic separator
(Conferences and Events at DigitalCommons@USU, 2018-05-15)
Hydraulic structures exhibiting strongly rotating flows are widely applied in the field of urban and wastewater
hydraulics. Given demographic, urban development and climate change challenge, such infrastructure will require ...
