LECA and expanded clay pebbles for Aquaponics
?Expanded clay ball
With performances of low density, light, heat preservation, heat insulation, good fire resistance, low bibulous rate, good resistance to heat shock and frost resistance and excellent resistance to alkali,?refractory castable ceramsite are widely used among building materials, chemical industry, oil and other industries and the range of its applications is getting wider and wider.

Expanded clay ball
is at present a kind of energy saving material, with the characters of light volume, high compressive strength, low thermal conductivity, no radiation.?corrosion resisting,?low bibulous rate, sound insulation, heat preservation and fire-resistant?, antifreeze and corrosion resistant. 400 and 500 class super light shale ceramsite is suitable for structure insulation concrete, 600 to 900 level ones are used for main structure concrete and also can be used for in situ concrete floor mat layer, high-rise building external wall, shear wall, elevator room wall, roof insulation, find slope and aboard live roof. It is widely used among ship building , bridge engineering, kiln project, BOT TOT OT and oil-field engineering and also the most ideal material to produce space truss lightweight partition board, roof insulation board, hollow block, acoustical tile and not to finalize the design refractory pouring.In recent years its application way is expanding and is using among thermal equipment, heat preservation library, highway, soilless culture greening and so on,

Ceramsite concrete’s density is small which density level is general for 800-1900 kg/m3, while commonly used ceramsite foam concrete density level is 300-1200kg/m3,?for the past few years super light ceramsite foam concrete is applied in constructional engineering. Due to the small density of ceramsite foam concrete, it usually can reduce the building weight about 25% and some even can reduce 30%-40% of the building’s total weight when used among building internal and external and wall level floor and pillar etc. Besides, in the view of structural element?take ceramsite foam concrete to the place of normal concrete can improve the member's bearing cutting ability. Thus using ceramsite foam concrete in the construction engineering has remarkable economic benefits.

- The?high?oxygen?levels?and?improved?drainage?provided?by?LECA?can?help?to?prevent?root?rot.
- It?helps?to?conserve?water?and?is?ideal?for?hydroponics?systems?due?to?the?fact?that?it?drains?quickly.
- Gives?roots?a?solid?foothold?so?that?they?can?become?secure.

- Can?be?easily?sterilised?if?transferring?plants?or?starting?a?new?project?with?existing?materials.
- The?main?disadvantage?is?that?LECA?doesn’t?hold?moisture?as?well?as?more?absorbent?mediums,?such?as?coco-coir,?although?this?can?be?combated?by?combining?it?with?other?mediums ?
