Alkali fusion of bauxite refining residue (red mud-RM) to produce low carbon cements
Pavia, Sara (2023)This paper creates hydraulic binders using waste and a low energy input. Cements are produced with a bauxite refining residue (red mud-RM), blended with limestone and lime, and fused at temperatures from 600 to 1200 °C. ... -
Application off Hemp-Lime Renders to Improve Insulation of Walls
Pavia, Sara; McGinn, J.; Kinnane, O. (2019)This paper measures the variation of thermal transmittance of solid brick walls triggered by the application of hemp-lime renders in an effort to enhance the insulating properties of buildings. Six renders with different ... -
Appraisal of Alum Sludge Waste for Low-Carbon, Calcium Aluminate Cement Production
Pavia, Sara (ISBN: 978-989-54499-3-4, 2023)Calcium aluminate cement (CAC) is the most used non-Portland cement, known for its rapid hardening and high thermal resistance. The difficulty in obtaining raw materials, mainly bauxite, has resulted in the current high ... -
An assessment of some properties of Roman cement
Pavia, Sara (2014) -
A binding composition and method for producing the binding composition.
Pavia, Sara (European patent agency, European patent agency, 2023)The present invention relates to binding compositions. Also disclosed are methods for producing the binding compositions and use of the binding compositions as binders, cements, and in concretes. Also disclosed are ... -
Characterisation of Irish sandstones used for building
Pavia, Sara (2014) -
Chemically treated plastic aggregates for eco‑friendly cement mortars
Pavia, Sara (2021)The use of waste plastic as aggregate in cement composites can solve the problem of the disposal of waste plastics in a sustainable way, and it reduces the need for extracting traditional materials like sand and gravel, ... -
A comparative study of the environmental impact of alkali activated and traditional materials
Pavia, Sara (2022)Many construction materials carry significant environmental impacts because they require high energy input and non-renewable materials for production, contributing to material depletion and greenhouse gas emissions. In ... -
Durability of Alkali-Activated Materials Made with a High-Calcium, Basic Slag
Pavia, Sara (2021)Alkali activated (AA) materials have been investigated for decades as an alternative to Portland cement (PC) products. Most consist of a silicate waste activated with alkalis, which leads to lower green-house gas emissions ... -
Effect of the early dissolution of Al-phases in reactive industrial wastes, on the setting times and rheology of sustainable binders
Pavia, Sara (2022)Aluminium-containing minerals in industrial wastes are relatively common, and they have potential as pozzolans or geopolymer precursors for the production of sustainable cements. The availability of reactive Al plays an ... -
Effectiveness of draught reduction measures at improving building air-tightness
Pavia, Sara; Walker, Rosanne (2018)The building sector has a serious detrimental impact on the environment and reducing building energy requirements is an important environmental priority. Draughts (unmanaged air infiltration and exfiltration in buildings) ... -
Energy performance, environmental impact and cost of a range of insulation materials
Pavia, Sara (2021)The need for the selection of an appropriate insulation is becoming more important as environmental problems continue to grow. This paper investigates insulation performance in terms of heating energy requirement, environmental ... -
An evaluation of the feasibility of industrial wastes and natural materials, as precursors, for the production of alkali activated materials (AAMs)
Pavia, Sara; Alelweet, Omar (2019)In order to face current compelling environmental problems affecting the planet, the construction industry needs to adapt. It is widely acknowledged that there is a need for durable, highperformance, low-greenhouse gas ... -
An Evaluation of the Feasibility of Several Industrial Wastes and Natural Materials, as Precursors, for the Production of Alkali Activated Materials
Pavia, Sara; Alelweet, Omar (2019)In order to face current compelling environmental problems affecting the planet, the construction industry needs to adapt. It is widely acknowledged that there is a need for durable, high-performance, low-greenhouse gas ... -
Fitness of a high-calcium slag for the production of alkali activated materials.
Pavia, Sara (ISBN: 978-989-54499-1-0, 2021)Alkali-activated (AA) materials are considered a more sustainable alternative to some traditional materials. This paper studies the feasibility of producing building materials by activating an Irish ground granulated blast ... -
Hot-lime-mixed hemp concretes
Pavia, Sara (2023)Hemp-lime composites are sustainable, low-carbon, non-loadbearing materials with outstanding thermal properties and high vapour permeability, used in new construction or thermal upgrades. The abundant pores in the hemp ... -
Hot-lime-mixed hemp concretes
Pavia, Sara (Springer, 2023)Hemp-lime composites are sustainable, low-carbon, non-loadbearing materials with outstanding thermal properties and high vapour permeability, used in new construction or thermal upgrades. The abundant pores in the ... -
Impact of hydration on the properties of hemp-lime concrete
Pavia, Sara (2014)
