ECA (Expanded Clay Aggregate) was developed about 1917 in Kansas City, Missouri, USA, to the production in a rotary kiln of a expanded aggregate known as ( LECA) Haydite which was used in the construction of USS Selma, an ocean-going ship launched in 1918. In Europe, LECA commenced in Denmark, Germany, Holland (Netherlands), UK and Middle East.
