Product Description
LECA has many advantage for agriculture and landscapes, it is used
as a growing medium in Hydroponics systems, blended with ... LECA
(Lightweight Expanded Clay Aggregate) is an aggregate made of
expanded clay at average ***0 C° in rotary kiln, the Yielding gases
are expanded by thousands of small bubbles as long as this
temperature and those will be provide many voids and honeycombs at
these round shape aggregates when melted materials become cold. The
clays and shales expanded were developed about ***7 in Kansas City,
Missouri, to the production in a rotary kin of a patented expanded
aggregate known as Haydite which was used in the construction of
USS Selma, an ocean-going ship launched in ***9 year. There
following in the USA the development of a series of aggregates
known as Gravelite, Perlite, Rocklite and etc. In Europe, LECA
commenced in Denmark, Germany, Holland (Netherlands) and the UK.
The manufactured aggregates are produce in various sizes; Four
usual grades are (**4) mm, (***0) mm, (****5) mm and mix grade ***5
mm which has **0 kg/m3 maxdensity, LECA boulder is a the bigger
size of LECA with ******0 mm size and less than **0 kg/m3 density.
Some of the important advantages of LECA aggregate are: lightness,
thermal insulation by low conductivity coefficient, soundproofing
by high acoustic resistance, moisture impermeable, incompressible
under permanent pressure and gravity loads, nondecomposition
against severe condition, fire resistant, Ph of nearly 7, freezing
and melting resistance, easy movement and transportation,
lightweight backfill and finishing, reduction of construction dead
load and earthquake lateral load, perfect sweet soil for plants,
best material for drainage and filtration. LECA is also used in
water treatment facilities for the filtration and purification of
municipal wastewater and drinking water as well as in other
filtering processes, including those for dealing with industrial
wastewater and fish farms. LECA has many advantage for agriculture
and landscapes, it is used as a growing medium in Hydroponics
systems, and blended with other growing mediums such as soil and
peat to improve drainage, retain water during periods of drought,
insulate roots during frost and provide roots with increased oxygen
levels promoting very vigorous growth. LECA can mix with normal
sweet soil in order to reduce the weight of plants and landscapes
soils. LECA aggregate has many applications in agriculture,
construction, geotechnical, civil and hydraulic engineering, Please
