Assessing the compressive strength and elastic modulus of high-performance GGBS concrete
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2022)The mechanical properties of High Performance Concrete are crucial for structural design to achieve expected advantages over conventional concrete. For example, the efficient prefabrication of precast concrete requires ... -
A comparative study of the environmental impact of alkali activated and traditional materials
(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 ... -
DEVELOPMENT OF SUSTAINABLE, ALKALI-ACTIVATED BINDERS FOR CONSTRUCTION
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2023)This work contributes to the design and production of alkali-activated materials (AAMs) of lower environmental impact than Portland cement (PC) products. AAM binders result from the reaction of an activator and a precursor. ... -
Durability of Alkali-Activated Materials Made with a High-Calcium, Basic Slag
(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 ... -
Long-Term Durability and Mechanical Performance of Alkali-Activated, Slag Cements
(2021)Alkali activated (AA) cements are considered less harmful to the environment than Portland cements (PC), as they consist of a silicate waste in lieu of a PC clinker, and this implies lower green-house gas emissions and ... -
Reactivity of raw, pyroprocessed and GGBS-blended alum sludge (AS) waste for sustainable cement production
(2023)This paper investigates AS waste to produce a construction binder of low environmental impact. It studies the reactivity of AS so that it can be used instead of traditional (higher impact) binders. Currently, most construction ...
