Expanded clay aggregate Wikipedia

Lightweight expanded clay aggregate (LECA) or expanded clay (exclay) is a lightweight aggregate made by heating clay to around 1,200 °C (2,190 °F) in a rotary kiln. The yielding gases expand the clay by thousands of small bubbles forming during heating producing a honeycomb structure. LECA has an approximately round or potato shape due to circular movement in the kiln and is available in different sizes and densities. LECA is used to make lightweight concrete products and other uses.

Expanded Clay Aggregate an overview ScienceDirect Topics

Expanded clay pellets (Fig. 8.11), most commonly known under the brand names LECA (acronym of light expanded clay aggregate) or LIAPOR (porous lias clay), also known as Hydroton and under the non-proprietary terms fired clay pebble, grow rocks, expanded clay (pellets) or hydrocorns, are small globes of burnt and expanded clay, used in construction and farming, and especially in hydroponics.

Rotary Kilns in Expanded Clay Aggregate Production

Expanded Clay Aggregate Thermal Treatment (Calcination or Sintering) The properties of expanded clay that make it ideal for use in a given application are achieved through a highly engineered production process. Clays are typically crushed, agglomerated and/or dried as a means of feedstock preparation, though this process can vary.

Finally, the product may be recycled to generating the material sources for the new material. Rashad AM (2018) Lightweight expanded clay aggregate as a building material—an overview. Constr

Expanded Clay Aggregate Scientific.Net

Abstract: The paper shows the possibility of production of the expanded clay aggregate with the use of electric steel melting slag up to 3.0 % produced by JSC “Oskol Electric Steel Works”. It was determined that at the temperature of 1170 °C the expanded clay aggregate with high strength properties and a high coefficient of swelling is formed.

Expanded Clay Techfil Pumice Production

Expanded clay is a lightweight aggregate manufactured from naturally occuring clay. It is non-toxic, disease free, chemically inert and has a neutral pH. It is used as a construction aggregate in lightweight concrete castings, floors and panels and as a loose lightweight fill in geotechnical applications.

Focus On Expanded Clay Plasmor

The Future Is Secure The Future Is Clay. Plasmor view the use of expanded clay as the key to the sustainable and ecological future of concrete block manufacture as it absolves the need for expensive and unreliable imports and lowers the use of virgin, hard, quarried aggregates such as limestone, granite, sand and gravel.
