ECA is an extremely light weight, strong and thermally insulating material. History: 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 most light weight aggregates as the size of aggregate increases the strength and bulk density of the aggregate decrease. Using very big size light weight aggregate with a lower strength results in a lower strength of the light weight concrete; therefore, biggest size of the light weight aggregate must be limited to 25 mm at most. 3. …
ECA® stands for Expanded Clay Aggregate. It is a type of lightweight aggregate made from natural clay.
