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 ...
Applications of biopolymers in dam construction and operation activities
(2015)
The investigation of innovative and sustainable solutions is a continuing concern within civil engineering activities. The use of environmentally friendly materials in place of traditional chemical substances is a key ...
Atterberg limits are not appropriate for peat soils
(2015)
This paper reports on the challenges associated with the determination of the Atterberg limits for peat, fundamental
issues regarding the appropriateness of Atterberg limit concepts applied to peat and peaty soils and ...
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 ...
Effect of chitin, chitosan and NaCMC biopolymers on the consistency limits of organic silt
(2024)
With global concerns on carbon emissions, there is increased need for various eco-friendly alternatives to conventional
(cement and lime) additives used in ground improvement applications. This paper investigates the ...
Municipal solid waste management under COVID-19: challenges and recommendations
(2021)
Covid-19 is proving to be an unprecedented disaster for human health, social contacts and the economy worldwide. It is evident that SARS-CoV-2 may spread through municipal solid waste (MSW), if collected, bagged, handled, ...
