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 ...
A comprehensive review of soil remolding toughness determination and its use in the classification of fine-grained soils
(2023)
The remolding toughness property of fine-grained soil has not been investigated that much, mainly because it has not lent easily to direct measurement, with soil toughness usually qualitatively described. In practical ...
Enzymatic-induced calcite precipitation (EICP) method for improving hydraulic erosion resistance of surface sand layer: a laboratory investigation
(2023)
As a bio-inspired calcite precipitation method, bio-grouting via enzymatic-induced calcite precipitation (EICP) uses free urease enzyme to catalyze the urea hydrolysis reaction. This soil stabilization approach is relatively ...
Use of fall-cone flow index for soil classification: a new plasticity chart
(2022)
Use of the Casagrande-style plasticity chart to classify fine-grained soils using Atterberg's liquid and plastic limits is ubiquitous in geotechnical engineering. This classification is dependent on the thread-rolling and ...
Reappraisal of the ASTM/AASHTO standard rolling device method for plastic limit determination of fine-grained soils
(2021)
Given its apparent limitations, various attempts have been made to develop alternative testing approaches to the standardized rolling-thread plastic limit (PLRT) method (for fine-grained soils), targeting higher degrees ...
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 ...
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 ...
