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).

SOUND INSULATION PROPERTIES OF EXPANDED CLAY AGGREGATE BUILDING CONSTRUCTION

Системные технологии, 2022
The purpose of this paper is to review the ability of expanded clay to serve as a sound insulator in structures. It presents an approach for a sound insulation lightweight concrete masonry unit made with lightweight expanded clay aggregate (LECA). Mansory produced from LECA is specially developed and suited for sound insulation between dwellings and ...

Expanded Clay and Shale Aggregates for Leachate Collection Systems

Journal of Geotechnical and Geoenvironmental Engineering, 1997
In regions dominated by high-carbonate aggregates, landfill owners are faced with using alternative materials for leachate collection systems. Expanded clay and shale, known as lightweight aggregates, contain essentially no carbonates and may provide a suitable alternative. We performed an engineering evaluation of expanded clay and shale aggregates to

Self-compacting lightweight concrete produced with expanded clay aggregate

Construction and Building Materials, 2012
Abstract The objective of this paper is to characterize self-compacting concretes produced with lightweight aggregates (SCLC) available in the Iberian Peninsula. The influence of different compositions on the self-compactability of SCLC is analyzed and some limits are suggested for their formulation.

Utilization of expanded clay aggregates in sustainable lightweight geopolymer concrete

Journal of Material Cycles and Waste Management, 2020
The lightweight sustainable construction composites prepared with the waste materials are enormously utilized for the construction activities. The geopolymer concrete (GPC) has emerged as the sustainable construction composite and holds potential to get modified as the lightweight composite.

Polyethylene Glycol-600/expanded clay aggregate with Alccofine1203 in concrete

Materials Today: Proceedings, 2021
Abstract The present work focuses on improving the thermal and mechanical properties of concrete using polyethylene Glycol-600/Expanded Clay Aggregate (ECA) with Alccofine1203. Immersion method was adopted with two different standards; ECA immersed at room temperature and higher temperatures (30 °C, 40 °C & 50 °C) for 8 h.

Drying of lightweight concrete produced from crushed expanded clay aggregates

Cement and Concrete Research, 1996
When crushed lightweight aggregates are used in lightweight aggregate concretes very small water amounts evaporate from the concrete even in a dry environment. It is shown that a large portion of the free batch water is absorbed into the pore structure of the crushed aggregates. The relative humidity in concrete pore structure diminishes faster than in

Mechanical properties of Light Expanded Clay Aggregated (LECA) filled tubes

Materials Letters, 2018
Abstract In this study, Light Expanded Clay Aggregated (LECA) foam elements were used as the filler material inside the empty thin-walled circular aluminum tube (ET). The mechanical properties and deformation/collapse mechanisms of the newly produced composite structures were evaluated under quasi-static uniaxial compressive loading conditions.

Lightweight masonry mortars made with expanded clay and recycled aggregates

Construction and Building Materials, 2016
Abstract One of the most extensive applications of recycled construction and demolition waste is as recycled aggregate in substitution of natural aggregate. An application for the fine fraction is investigated in this study by preparing lightweight mortars with different types of fine recycled aggregate from concrete waste and rubble.

Chemisorption of hydrogen sulphide and methanethiol by light expanded clay aggregates (Leca)

Chemosphere, 2013
Removal of volatile sulphur compounds from livestock waste air by biological air filtration may be enhanced by application of packing materials with reactive properties. In this study, light expanded clay aggregates (Leca) was tested with respect to sorption and potential chemical degradation of H2S, Methanethiol (MT) and Dimethyl sulphide (DMS).
