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

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.

Experimental study on lightweight concrete made with expanded clay aggregate and lime

Innovative Infrastructure Solutions, 2021
Prefabricated 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, 2021
Abstract 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, 2016
The 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).

Mix design of structural lightweight self-compacting concrete incorporating coarse lightweight expanded clay aggregates

Construction and Building Materials, 2018
Abstract This paper reports an experimental study that aimed to define the parameters for the mix design of structural lightweight self-compacting concrete (LWSCC) incorporating coarse lightweight expanded clay aggregates and natural sand. The starting point was the methodology proposed by Nepomuceno et al.

Methodology for the Design of Lightweight Concrete with Expanded Clay Aggregates

The Masonry Society Journal, 2005
The increasing use in Portugal of masonry blocks composed of lightweight concrete with expanded clay aggregates emphases the need to optimize the mix design in order to achieve desired concrete properties. To date, the research on these lightweight concretes has been of limited value because the specificities of their production with vibrant-compressor

The Study of Lightweight Expanded Clay Aggregate from Industrial Waste

Chiang Mai Journal of Science
This study aims to investigate the utilization of lightweight expanded clay aggregate (LECA) produced by combining clay with industrial waste as a planting material for soil moisture retenti on. Lightweight expanded clay aggregate is a growing media material composed of clay pellets subjected to high temperatures. This substance is created by combining

Lightweight expanded clay aggregate as a building material – An overview

Construction and Building Materials, 2018
Abstract 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

Influence of Expanded Clay Aggregates in Abrasion Resistance of Lightweight Concrete

SP-253: Fifth ACI/CANMET/IBRACON Int'l Conference on High-Performance Concrete Structures & Materials, 2008
Durability is one of the key factors considered in the specification of concrete for most of its applications. When applied to industrial floors, road pavements, and sidewalks, abrasion wearing impairs the concrete performance. This work is focused on the abrasion resistance of lightweight concrete produced with expanded clay, comparing it to the ...
