Appraisal of novel power-based extrusion methodology for consistency limits determinations of fine-grained soils
(Civil Engineering Research Association of Ireland, 2022)The consistency limits (liquid limit LL and plastic limit PL) are among the most commonly performed tests in geotechnical engineering practice, being used for classification of fine-grained soils and in deducing other ... -
Discussion of ?Behaviour of a foam mixture as a lightweight construction material? [Int J of Geosynth and Ground Eng (2021) 7(3), 51]
(2022)The Discussers read the Authors’ paper with interest, having recently published findings on the geotechnical behaviour/properties of clayey sand–expanded polystyrene (EPS) beads mixtures [1]. The Authors purport a ‘new’ ... -
Engineering reactive clay systems by ground rubber replacement and polyacrylamide treatment
(2019)This study investigates the combined performance of ground rubber (GR), the additive, and polyacrylamide (PAM), the binder, as a sustainable solution towards ameliorating the inferior geotechnical attributes of an expansive ... -
Environmental geotechnics: challenges and opportunities in the post-COVID-19 world
(2021)The outbreak of the coronavirus disease 2019 (Covid-19) pandemic not only has created a health crisis across the world but is also expected to impact negatively the global economy and societies at a scale that is maybe ... -
Improved geotechnical behavior of an expansive soil amended with tire-derived aggregates having different gradations
(2020)This experimental laboratory study examines the potential use of tire-derived aggregate (TDA) products as an additive to alleviate the inferior geotechnical properties of a subgrade deposit of clay soil with high ... -
Intermittent swelling and shrinkage of a highly expansive soil treated with polyacrylamide
(2022)This laboratory study examines the potential use of an anionic polyacrylamide (PAM)-based material as an environmentally sustainable additive for the stabilization of an expansive soil from South Australia. The experimental ... -
Modeling the compaction characteristics of fine-grained soils blended with tire-derived aggregates
(2021)This study aims at modeling the compaction characteristics of fine-grained soils blended with sand-sized (0.075–4.75 mm) recycled tire-derived aggregates (TDAs). Model development and calibration were performed using a ... -
An objective framework for determination of the air-entry value from the soil?water characteristic curve
(2021)The air-entry value (AEV) suction, marking the transition between saturated and unsaturated soil mechanics, is arguably the most important parameter interpreted from the soil–water characteristic curve (SWCC); its accurate ... -
Radon Potential as a diagnostic tool for indoor radon hazard mapping
(2019)At over 56% of the annual effective dose, radon is the primary source of ionizing radiation exposure received by the Irish population. Although the average indoor radon concentration in Ireland has been reduced since ... -
Reappraisal of soil extrusion for geomechanical characterisation
(2019)Reverse extrusion has been promoted over the past four decades for remoulded undrained shear strength (s u) measurement and consistency-limit determinations. The technique employs a uniaxial-compression test machine to set ... -
Recent advances in nature?inspired solutions for ground engineering (NiSE)
(2022)The ground is a natural grand system; it is composed of myriad constituents that aggregate to form several geologic and biogenic systems. These systems operate independently and interplay harmoniously via important networked ... -
Review of recent developments and understanding of Atterberg limits determinations
(2021)Among the most commonly specified tests in the geotechnical engineering industry, the liquid limit and plastic limit tests are principally used for (i) deducing useful design parameter values from existing correlations ... -
Stabilization of sand with colloidal nano-silica hydrosols
(2020)Colloidal nano-silica (NS) hydrosols are electrochemically stabilized, polymerized amorphous silica in low viscosity solutions, and in the form of hydrated gels, silica globules or pellicles.Compared to applications ... -
A study of natural radioactivity levels and radon/thoron release potential of bedrock and soil in southeastern ireland', International Journal of Environmental Research and Public Health
(2021)Radon (222Rn) and thoron (220Rn) account for almost two-thirds of the annual average radiation dose received by the Irish population. A detailed study of natural radioactivity levels and radon and thoron exhalation rates ...
