Technology for producing keramzit from low expandable clay

Glass and Ceramics, 2012
The possibility of producing low-density, high-strength keramzit from low expandable clay raw material using lignin-alkaline reagent (LAR) is investigated. The particulars of the formation of the porous structure of keramzit granules using different temperature–time regimes and its effect on the physical–mechanical properties of the material are ...

Water retention of light expanded clay amendment

Communications in Soil Science and Plant Analysis, 1998
Abstract Shallow‐drained horticultural soils utilized in containers, sporting areas, and landscape sites tend to retain excess water and thereby be poorly aerated as a consequence of capillary retention following irrigation or precipitation. This problem is usually corrected by soil physical amendment with coarse‐textured particulates to add large ...

Partitioning of Binary Solvents on Charged Expandable Clays

Clays and Clay Minerals, 1996
Abstract The present paper represents an extension of recent work that considered the partitioning response of binary solvents placed into contact with charged, expandable clays. Previous theoretical work yielded a model of partitioning by performing a thermodynamic analysis, involving the work of polarization, on a binary solvent ...

Vapor adsorption on expanding and nonexpanding clay minerals

Journal of Colloid and Interface Science, 1979
Adsorption of water and cyclohexane vapors at 35°C was measured on montmorillonite (an expanding-type clay mineral) and on illite (a nonexpanding clay mineral), both heated in vacuo at various temperatures for 5 hr. Specific surface areas were estimated from the BET method (SBET), and from the cumulative values of pore structure analysis (Scum). Water,

Mechanical characterization of lightweight expanded clay particles

Materials Research Proceedings
Abstract. The objective of the research is to study the mechanical behavior of crushable particles containing an internal porosity. To ease the visualization of grains’ crushing, expanded clay aggregates (LECA) was selected as a model material due to the brittle behavior of its particles and its high internal porosity. Identification of LECA’s physical

Development of expandability charts for Ankara Kalecik Clay

Applied Clay Science, 2014
Abstract The main aim of this study is to establish optimum working conditions and to propose expandability charts for Kalecik Clay using expansion ratio versus unit volume weight values via a statistical computer program (Design Expert 7.0). First of all, some suitable samples were collected from the Kalecik County (Ankara, Turkey).
