Lightweight Expanded Clay Aggregate LECA Production Line Sand
Production Plan
Description:
Lightweight expanded clay aggregate (LECA Production line) or
expanded clay (exclay) is a light weight aggregate made by heating
clay to around 1,200 °C (2,190 °F) in a rotary kiln. The yielding
gases expand the clay by thousands of small bubbles forming during
heating producing a honeycomb structure. LECA has an approximately
round or potato shape due to circular movement in the kiln, and is
available in different sizes and densities. LECA is used to make
lightweight concrete products and other uses.
ECA is usually produced in different sizes and densities from 0.1
millimetres (0.0039 in) up to 25 millimetres (0.98 in),commonly 0-4
mm, 4-10 mm, 10-25 mm and densities of 250, 280, 330, and 510
kg/m3. LECA boulder is the biggest size of LECA with 100–500 mm
size and 500 kg/m3 density.
Some characteristics of LECA(LECA production line) are: lightness,
thermal insulation by low conductivity coefficient (as low as 0.097
W/mK[1]), soundproofing by high acoustic resistance, moisture
impermeable, incompressible under permanent pressure and gravity
loads, non–decomposition 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, material for drainage and filtration.

Usage of LECA:
Common uses are in concrete blocks, concrete slabs, geotechnical
fillings, lightweight concrete, water treatment, hydroponics,
aquaponics and hydroculture.
LECA is a versatile material, and is utilized in an 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 addition it
can reduce earth pressure by 75% 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 uses in 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 be mixed with heavy
soil in order to reduce the weight of plants and landscapes soils.
