Expanded Clay Aggregate, ECA, Leca,Railway Noise Reduction,

The gradation of the Expanded Clay Aggregate (ECA) has a great effect on the acoustic/sound absorption performance of the porous concrete, with high aggregate gradation of 2 - 3 mm. The compaction index and fiber content affect both the acoustic/sound absorption and strength property of the porous concrete, with value of 0.4% and 1.8% respectively.

Expanded Clay Aggregate (ECA ®) or Lightweight Expanded Clay Aggregate (LECA) is a round pellet structure produced by firing natural clay at temperature of 1200°C. The result is a hard, honeycombed structure of interconnecting voids within the aggregate. The particles formed are round in shape and generally range in size from 0-30 mm.
