Effect of expandable clays and cometabolism on PAH biodegradability

Environmental Science and Pollution Research, 2003
Pyrene and phenanthrene degradation was examined in both single and binary slurry systems for three different natural soils. It was found that the amount of total expandable clays (smectite and vermiculite) was in a good agreement with the achieved rate and extent of biodegradation.

Microstructural Analysis of Iberian Expanded Clay Aggregates

Microscopy and Microanalysis, 2012
AbstractThis article presents a detailed study of the microstructure of Iberian expanded clay lightweight aggregates (LWA). Other than more commonly used mercury porosimetry (MP) and water absorption methods, the experimental study involves optical microscopy, scanning electron microscopy (SEM), and microtomography (μ-CT).

Rupelian Boom clay as raw material for expanded clay manufacturing

Applied Clay Science, 1993
Abstract The Rupelian Boom clay has been investigated with respect to its bloating characteristics. In industrial practice, it was found that too much organic matter has a negative impact on bloating and that iron compounds have to be added to facilitate the expansion process.

NDT of LWC with Expanded Clay

2011
Nowadays, light-weight concrete (lwc) is increasingly used in construction, namely lwc with aggregates of expanded clay type called Liapor. It is often necessary to perform tests for the characteristics of cast-in-place concrete during building construction as well as after the construction.

The application of sewage sludge as an expanding agent in the production of lightweight expanded clay aggregate mass

Environmental Technology, 2011
Sewage sludge can be used as an expanding agent in the production of lightweight expanded clay aggregate (LECA) mass. The addition of sewage sludge increases the total porosity and decreases the bulk density of a sinter. The addition of sewage sludge to a raw material used in the production of LECA enabled a decrease in the burning temperature for the ...

The acoustical properties of consolidated expanded clay granulates

Applied Acoustics, 2006
The paper presents a systematic study of acoustic and non-acoustic properties of consolidated porous samples of expanded clay granulates. The effect of the particle size on the acoustic performance of consolidated expanded clays is investigated experimentally and theoretically. This work involves a comparison of the measured and predicted values of the

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,

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 ...

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).
