varying sizes. The inside of the aggregate has a black sponge texture with 73–88 % porosity. The high porosity of the aggregate causes improvement in some properties such as low weight, low heat conductivity, sonic loss, and high resistance against firing. The aggregates have a coating with a thickness of about 50–100 µm. The

Pebble density. The density of your clay pebbles is an important factor in how it will perform as a potting medium. Pebble density is rarely advertised directly for most LECA products, but sometimes brands will offer an average porosity of their product. Porosity is a measure of the empty space within the structure of the clay pebble. A good ...
