Light Expanded Clay Aggregate, From the earth to fire, this is how
Leca is created. Please Contact us to know more about it. 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/m3maxdensity, LECA boulder is a the bigger size
of LECA with ******0 mm size and **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 an incredibly
versatile material, and is utilized in an ever-increasing number of
applications. In the construction industry, it is used extensively
in the production of lightweight concrete, blocks and precast or
incast structural elements (panels, partitions, bricks and light
tiles. LECA used in structural backfill against foundations,
retaining walls, bridge abutments etc., in additional it can reduce
earth pressure by *5% compared with conventional materials, and
also increases ground stability while reducing settlement and land
deformation. LECA can drainage the surface water and groundwater to
control ground water pressure. LECA grout can be used for flooring
(finishing) and roofing with thermal and sound insulation. 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 has many advantage for agriculture and
