Intrinsic soil properties, such as the Atterberg limits, are essential factors influencing the mechanical behaviour of the fine-grained soils. In this study, a series of long-term multiple-stage
Mineralogical study of clays from Dobrodo, Serbia, for use in ceramics
Abstract This study focuses on the mineralogical characterization of four raw clay samples from Dobrodo deposit, Serbia. Several analytical methods were applied to determine the chemical and
The integration of grain-size distribution and plasticity parameters for characterizing and classifying unconsolidated fine-grained sediments
Grain-size distribution (GSD) characteristics are often used to classify different types of sediment and to understand how variations in depositional processes affect mechanical behavior. However,
The Alternatives to Traditional Materials for Subsoil Stabilization and Embankments
Fly ashes and ash-slag mixtures have also comparable mechanical properties with sands, which in combination with multiple other benefits, make them suitable fill materials for embankments, especially considering the necessity for sustainable development.
Pedogenesis of Mt. Sumbing Volcanic Ash above The Alteration Clay Layer in The Formation of Landslide Susceptible Soils in Bompon Sub-Watershed
Numerous researches on landslides have been carried out by many researches. However, studies on soil physical properties related to landslides potential in volcanic area are still rare. The objective
Review: Progress with Functional Materials Based on Loess Particles
Loess is a large-scale deposit which is easy to mine and widely distributed on the epipedon. The clay fraction of loess, also known as ‘loessial clay’, is a very important component of loess which
Review of Recent Developments and Understanding of Atterberg Limits Determinations
This updated state-of-the-art review paper gives a comprehensive presentation of salient latest research and understanding of soil consistency Limits determinations/measurement, elaborating concisely on the many standardized and proposed experimental testing approaches, their various fundamental aspects and possibly pitfalls, as well as some very recent alternative proposals for consistency limits determinations.

This study proposes a new soil classification based on the different behaviour of two fractions that can generally be distinguished in clayey soils: the “active, binder” fraction composed of clay
Definition of Clay and Clay Mineral: Joint Report of the Aipea Nomenclature and CMS Nomenclature Committees
The definition of"clay" was first formalized in 1546 by Agricola. It has been revised many times since, although the fundamentals involving plasticity, particle size, and hardening on firing were
Abstract The plastic properties of clays are sufficiently variable to offer a simple but practical aid to identification. This can be done by using their Atterberg 'plastic limit' and 'plasticity
The proposed activity chart, which aims to classify soils (< 425 μm) using the Atterberg limits, differs from the plasticity chart recently proposed by the author because the inorganic soils with
Plastic Limit and Other Consistency Parameters by a Bending Method and Interpretation of Plasticity Classification in Soils
Although plastic limit, PL, is one of the parameters more widely used in the field of geotechnical engineering, the existing method for its determination (the thread-rolling test) is characterized by
