Expanded Clay Aggregate, ECA, Leca,Porous Concrete Acoustic

Porous Concrete Acoustic Structures

Using Expanded Clay Aggregate (ECA) Concrete Block As Sound/Acoustic Insulator:

  • The particular structure of Expanded Clay Aggregate (ECA) makes it a perfect component for prefabricated porous concrete acoustic structures of various sizes and appearance,
  • Expanded Clay Aggregate (ECA) is suitable for the use as:     
        A Sound-absorbent facing for existing walls
        A Sound-absorbent noise insulating acoustic barrier
  • Expanded Clay Aggregate (ECA) is used for making hollow blocks, solid blocks of lightweight concrete which are used in construction of buildings, railways, bridges and so on.
  • Expanded Clay Aggregate (ECA) solid blocks are suitable for basement, inner-leaf walls, partitions, foundations and outer walls.

Using Expanded Clay Aggregate in Light-weight Filling as a Sound/Acoustic Insulator:
  • Expanded Clay Aggregate (ECA) is the perfect solution for a light-weight fill with great mechanical and acoustical properties.
  • Expanded Clay Aggregate (ECA) should be applied loose, and surfaces moisten with cement run-off, to enhance the insulation characteristics.
  • APPLICATION of Expanded Clay Aggregate as LIGHTWEIGHT FILLING



Using Expanded Clay Aggregate (ECA) Concrete Block As Sound/Acoustic Insulator:
