Harris 2.5 lb. Leca Expanded Clay Pebbles

LECA, also known as lightweight expanded clay aggregate, is a collection of kiln-fired clay baked into round balls. Used in all types of gardening functions, these porous pebbles allow for superior drainage and air circulation so roots get plenty of oxygen. They are pH neutral, non-flammable, odorless, and do not decay or shrink.

Recycling of an industrial sludge and marine clay as light-weight

In an attempt to find ways to reduce importation of raw materials and the waste sent to landfill, light weight aggregates were produced from marine clay and a CaF(2)-rich semiconductor industry sludge. Aggregates were produced in a bench-scale rotary kiln with three clay/sludge loadings (90/10, 70/30 and 50/50%).
