Durability of Lightweight Expanded Clay Aggregate Concrete
Procedia Engineering, 2013 AbstractThe paper describes a development and use of lightweight concrete and lightweight self-compacting concrete using artificial lightweight aggregate based on expanded clay for ready mix concrete and precast elements. The objective of this research was to evaluate the lightweight concrete on durability of concretes placed in chemically aggressive ...

Effect of temperature curing on lightweight expanded clay aggregate concrete
Materials Today: Proceedings, 2021 Abstract Lightweight Aggregate Concrete is usually a mix of Lightweight Aggregates and admixtures. This paper is focused on use of Lightweight Expanded Clay Aggregate (LECA) for the development of structural Lightweight Concrete. The present investigation was carried out by replacing LECA with 30% of Normal Weight Aggregate (NWA) with different water

Behaviour Of Lightweight Expanded Clay Aggregate Concrete Exposed To High Temperatures
, 2014 This paper is concerning the issues of behaviour of lightweight expanded clay aggregates concrete exposed to high temperature. Lightweight aggregates from expanded clay are produced by firing of row material up to temperature 1050°C. Lightweight aggregates have suitable properties in terms of volume stability, when exposed to temperatures up to 1050°C,

Methodology for the Design of Lightweight Concrete with Expanded Clay Aggregates [PDF]
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

Modelling of Projectile Penetration into Lightweight Expanded Clay Aggregate [PDF]
Journal of Dynamic Behavior of Materials, 2016 This work presents a phenomenological model for estimating projectile penetration into granular lightweight expanded clay aggregate often known as Lightweight expanded clay aggregate (LECA). Laboratory scale penetration experiments in the low-velocity regime performed using LECA are presented. A penetration model based on the mass and momentum balances
