Lightweight expanded clay aggregate properties based on laboratory testing

Construction and Building Materials, 2021
Abstract 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.

Physical and Mechanical Properties of Lightweight Expanded Clay Aggregate (LECA) [PDF]

MATEC Web of Conferences, 2018
Lightweight aggregate is the generic name of a group of aggregates having a relative density lower than normal aggregates (natural sand, gravel, and crushed stone), sometimes is referred to as low density aggregate. Depending on the source and the method

Properties and homogeneity of a commercial light expanded clay aggregate [PDF]

Cerâmica
In the present work, an exhaustive analysis of an Argentinian commercial LECA with a multi-technique approach was successfully carried out. Five sub-types of samples were considered to study the degree of macroscopic homogeneity of the LECAs, which ...
