What are the granulometric sizes range available for Expanded Clay Aggregate (ECA) or Lightweight Expanded Clay Aggregate (LECA) ?

Expanded clay Aggregate (ECA) is available in a wide range of granulometric sizes. The most suitable sizes for geotechnical use are 2-8 mm, 8-15 mm, 15-30 mm and in many a applications 0-30 mm depending on the requirements of applications. Specific granulometric sizes can be prepared on specific ...



What is the specific weight of Expanded Clay Aggregate (ECA) and its dry density ?

Expanded clay Aggregate (ECA) has a honeycombed structure and high percentage of void which results in the density of Expanded Clay Aggregate being considerably lower than that of traditional aggregates ( For e.g. in the case of aggregate size 8-15 mm and 15-30 mm, the dry density of the product ...



How do we derive the angle of friction of Expanded Clay Aggregate for Geotechnical Application design work ?

The angle of friction of limitless expanded clay aggregate (eca) is obtained from triaxial tests by varying the lateral confining pressure of the aggregate and its degree of compaction.
For design purposes, with a confining pressure of 200 kPa (which is typical of the most important geotec...



How does one determine the surface stiffness of expanded clay aggregate embankments ?

The surface stiffness of expanded clay embankments is determined by plate load testing.
The stiffness values obtainable will depend on the technical solution chosen, the grain size of the expanded clay, and the degree of compaction.
The various methods for constructing an embankment...



Can you let us know about the Water absorption and drainage properties of Expanded Clay Aggregate ?

Expanded Clay Aggregate (ECA) is a round pellet structure produced by firing natural clay at temperature of 1200°C. The result is a hard, honeycombed structure of interconnecting voids within the aggregate. The particles formed are round in shape and generally range in size from 0-30 mm. Thes...
