Microstructural Analysis of Iberian Expanded Clay

2012-10-3  For expanded clay aggregates of 1,200 kg/m 3, Faust and Beck (Reference Faust and Beck 1999) observed median diameters of 1.2 μm, similar to those found in this study. Taking the bottleneck effects into account, it is reasonable to conclude that most of the open porosity occurs for pores larger than 0.1 to 1 μm.

Estimation of water absorbed by expanding clay

2012-4-24  The estimation of water absorption in aggregates is still one of the major challenges related to the production of structural lightweight aggregate concrete (SLWAC). At present these predictions are only based on common practice and a more soundly based approach is required. Aggregate absorption is mainly affected by its microstructure, surface characteristics, percentage of broken particles

What is Expanded Clay Aggregate? Definition from

2021-9-3  Expanded or expandable clay aggregate is a commonly used hydroponic grow medium. It is a lightweight aggregate that is heated in a kiln oven to a temperature of 2,910 degrees Fahrenheit (1,200 degrees Celsius). Once the aggregate is heated, it releases gases, which create small bubbles that make a honeycomb-like structure inside of the aggregate.
