ECA Construction Blocks

Expanded Clay Aggregate (ECA) Construction Masonry Block

Expanded Clay Aggregate (ECA) BLOCKS are masonry units manufactured using Expanded Clay Aggregate (ECA), Class F fly ash and Cement. They are used for non-load bearing wall masonry.

After application of a high-performance innovative technology of manufacturing and post curing process, Expanded Clay Aggregate (ECA) BLOCKS gains superior material properties.

It also offers no reduced shrinkage and a superior fire and chemical resistance adding to several advantages including durability, versatility, speed and ease-of-use as well as cost benefits and environmental considerations.
