This paper examines and assesses predictive methods for the saturated hydraulic
conductivity of soils. The soil definition is that of engineering. It is not that of soil science and …

Flyash, an industrial by-product, rich in silica and alumina contents, has been known to be a
useful material for synthesizing zeolites. These zeolites are minerals of alumino silicate …

In this study, a carbon-based solid acid catalyst was prepared using the de-oiled Jatropha
curcas (JC) seed cake waste. The catalyst was consequently used to esterify the JC oil in …

The application of biochar is promising for improving the physical, chemical and
hydrological properties of soil. However, there are few studies regarding the influence of …

Clay soil is a common building foundation material, and its permeability is very important for
the safety of foundation pits and the later settlement of buildings. However, the traditional …

Problems related to unsaturated soils are frequently encountered in geotechnical or
environmental engineering works. In most cases, for simplicity, one can study the problems …

Application of the methylene blue test methods in determining soil properties, including
specific surface area (SSA), cation exchange capacity (CEC), swell index, and swell …

The main objective of this research was to investigate the effect of coal waste powder as
filler material in hot mix asphalt. After sampling the coal waste material from a coal washing …

Periodic redox condition changes in acidic paddy soils substantially induce the
biogeochemical redox cycling, and consequently affect Cd availability. However, the …

The adsorptive properties of natural and Na-enriched bentonite in zinc rich aqueous
environment have been studied. The results show that adsorption behavior of both …
