Lightweight expanded clay aggregate properties based on laboratory testing
Construction and Building Materials, 2021Abstract Lightweight expanded clay aggregate (LECA) is a manufactured aggregate with many uses in construction, such as aggregate for the lightweight concrete or like geotechnical fill. The properties of the material may vary depending on the manufacturer or the applications envisaged for the aggregate.

Lightweight expanded clay aggregate as a building material – An overview
Construction and Building Materials, 2018Abstract LECA is the abbreviation of lightweight expanded clay aggregate. LECA is produced from special plastic clay with no or very little content of lime. The clay is dried, heated and burned in rotary kilns at 1100–1300 °C. LECA is porous ceramic product with a uniform pore structure with almost potato shape or round shape due to the kiln circular

Utilization of expanded clay aggregates in sustainable lightweight geopolymer concrete
Journal of Material Cycles and Waste Management, 2020The 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.

Self-compacting lightweight concrete produced with expanded clay aggregate
Construction and Building Materials, 2012Abstract 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.

Lightweight Expanded Clay Aggregate (LECA) as replacement materials for geotechnical application
Physics and Chemistry of the Earth, Parts A/B/C, 2023Settlement is a common geotechnical problem occurs in soft soils. The replacement method is the easiest way to improve this problematic soil. This technique is carried out by removing the unwanted part of the soil and replacing it with a more suitable material or soil.

Drying of lightweight concrete produced from crushed expanded clay aggregates
Cement and Concrete Research, 1996When 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

Lightweight masonry mortars made with expanded clay and recycled aggregates
Construction and Building Materials, 2016Abstract 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.

Experimental study on lightweight concrete made with expanded clay aggregate and lime
Innovative Infrastructure Solutions, 2021Prefabricated panel walls have been widely used in building construction due to their excellent structural benefits over other construction methods. However, the heavyweight of thick wall panels is the main barrier for connecting, transporting, and handling prefabricated wall elements.

Structural performance of fiber-reinforced lightweight concrete slabs with expanded clay aggregate
Materials Today: Proceedings, 2021Abstract The main objectives of this study are to inspect experimentally the structural behavior of fiber reinforced lightweight concrete two-way slab through examining the influence of different fibers combinations on the initial crack load, ultimate load, strain distribution, maximum deflection and ductility factor. The experimental program of this

Tests on direct tensile characteristics of expanded clay lightweight aggregate concrete
Magazine of Concrete Research, 2016The tensile characteristics of lightweight aggregate concrete under direct tension were examined with a view to enhancing the utilisation of artificially expanded clay granules as secondary aggregates. Ready-mixed concrete specimens were classified into two groups: all-lightweight concrete (ALWC) and sand-lightweight concrete (SLWC).
