Comment on “A new approach to stabilization of calcareous dune sand”
(2023)The Discussers read with interest the paper by Ghadr et al. (2022) (the Authors); the research topic being particularly important for various regions of the world regarding the main goals of dust suppression and wind-driven ... -
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’ ... -
Discussion: Effects of plastic waste materials on geotechnical properties of clayey soil [DOI: 10.1007/s40515‑020‑00145‑4]
(2023)The paper under discussion (by Hassan et al. (2021)) presents a comprehensive set of experimental results from standard geotechnical laboratory tests performed on a low-plasticity clay soil (CL) amended with between 1% and ... -
Effects of cement kiln dust on physicochemical and geomechanical properties of loess soil, Semnan Province, Iran
(2022)For problematic soils, conventional (cement and lime) additives can provide the necessary improvements in geomechanical properties for various infrastructure constructions. However, these additives have a high environmental ... -
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 ... -
Geomechanical behaviour of uncemented expanded polystyrene (EPS) beads?clayey soil mixtures as lightweight fill
(2021)Lightweight fill can be advantageous in embankment construction for the purposes ofreducing the (i) bearing pressures on the underlying soil foundation, (ii) destabilizing moments forconstructed earthen slopes, and (iii) ... -
Geotechnical investigation of low-plasticity organic soil treated with nano-calcium carbonate
(2023)Soil stabilization using nanomaterials is an emerging research area although, to date, its investigation has mostly been laboratory-based and therefore requires extensive study for transfer to practical field applications. ... -
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 ... -
Predicting the Compactability of Artificially Cemented Fine‑Grained Soils Blended with Waste‑Tire‑Derived Aggregates
(2023)This study investigates the possibility of extending the specific gravity ratio (SGR) modeling framework, originally developed for predicting the compaction properties of unamended fine-grained soils (with no binder) ... -
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 ... -
Reducing the erodibility of sandy soils engineered by cyanobacteria inoculation: a laboratory investigation
(2023)Windblown and water-induced erosion cause substantial soil losses worldwide, especially for drylands. Any sustainable management program that increases soil organic matter and improves the stability of the crustal layer ... -
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 ... -
Sustainable environmental geotechnics practices for a green economy
(2022)The revitalisation of the global economy after the Covid-19 era presents environmental geotechnics with the opportunity to reinforce the need for a change in paradigm towards a green, circular economy and to promote ...
