La description
It is a type of concrete which whole or some part of ordinary
aggregate replacing with an artificial lightweight aggregate.
Structural or semi-structural Light Weight Concrete (LWC) has been
used in usual civil engineering applications as a very convenient
alternative to conventional concrete. Structural lightweight
concrete made with rotary kiln produced structural lightweight
aggregate solves weight and durability problems in buildings and
exposed structures. Structural lightweight concrete has strengths
comparable to normal weight concrete, yet is typically *5% to *5%
lighter. Structural lightweight concrete offers design flexibility
and substantial cost savings by providing less dead load, improved
seismic structural response, longer spans, better fire ratings,
thinner sections, decreased story height, smaller size structural
members, less reinforcing steel, and lower foundations costs, also
LWC can easily pumping to higher floors. Structural lightweight
concrete precast elements have reduced trucking and placement
costs. Concrete using ESCS lightweight aggregate has better thermal
properties, higher fire ratings, reduced autogenously shrinkage,
excellent freezing and thawing durability, improved contact zone
between aggregate and cement matrix, less micro-cracking asa result
of better elastic compatibility, more blast resistant, and has
better shock and sound absorption, High-Performance lightweight
aggregate concrete also has less cracking, improved skid resistance
and is readily placed by the concrete pumping method. LECA mortar
can be used like normal mortar for built of block wall or all
masonry products with all advantage of LECA, for example one of the
best usages of LECA grout or mortar is to protect steel structural
elements for fire and corrosion attacking. LECA aggregate are
produced according the ASTM C***0 & C***1 and LECA concrete
shall meet guide line of ASTM **1.2 & **8. The mostly of uses
lightweight concrete are as following subjects: * LECA concrete can
be used in different type of slabs in RC frame or deck of steel
frame structures, beams or columns as RC elements or as fire
protection of steel members * Post tension slab or beam system,
Bridge decks, piers & AASHTO griders * Specified density
concrete, it can be ordered as structural engineer requirement with
different density and obviously different compressing strength fc
which mix design could be prepared accordingly. * Lightweight
concrete precast & prestressed elements (beams, double-tees,
tilt-up walls, raised access floor panel planks, hog slats, utility
vaults, pipes, ornamentals, etc.) * LECA concrete or grout can
create packages of lightweight, safe and insulating roof and also
it allows for creation of slopes for the drainage of rain water and
of ballasting of waterproof surfaces. * Marine structures, floating
docks, ships, & offshore oil * Asphalt pavements (rural, city
& freeway) * Lightweight asphalt bituminous surface treatments,
lightweight chip seal, seal coat, etc
