Sintagg-FLY ASH LIGHT WEIGHT AGGREGATES

| Size : 4/8mm , 8-16mm |
Sintagg- FlyAsh based lightweight (Low Density )aggregate by sintering process, can be as a substitute for normal crushed stone
aggregate, in making of concrete for structural and other applications. The focus is empowering environment by making
productive use of mounting stocks of fly ash – a nuisance by-product of thermal
power plants.

In addition to some potential benefits to the concrete itself,
the use of fly ash as a lightweight aggregate in place of natural
aggregate offers a wealth of benefits both economically and environmentally.

The
normal stone aggregate is a dense material, which makes heavy density concrete.
The structural engineers would like to get alternative lighter density
aggregate, so as to produce lightweight concrete. Use of lightweight concrete,
as a substitute for normal dense concrete, reduces weight of structural elements
like beams, columns, slabs, foundations, thereby saving on cost of foundations
and reinforcing steel needed for the structure.
Other coincidental
benefits include fewer delivery trucks and reduced labour in-put. Long term
benefits in some instances, as in the case of exterior walls and roofs, can be
even greater than the initial savings,due to its thermal insulation properties .
Lightweight
Aggregates are sought after product not only for production of Lightweight
concrete, but more recently as application in horticulture. As a horticultural
application, it is not only 30% lighter as a growing medium, but the porous cavities
within the aggregate, become reservoirs of irrigation water and fertilizer
(because of higher water absorption capacity) thereby reducing operation and
maintenance costs. They are also very clean and used as common growing medium
for planters deployed in household and offices.
ECONOMIC
BENEFITS
The use of fly ash as a lightweight aggregate can offer a wide
range of economic advantages; not only is the source of fly ash (power plants)
close in proximity to the demand, providing a readily available aggregate
source at hand, but it can also be a much-needed economic source in areas
where natural aggregates are not widely available.
The most critical advantage to using a lightweight aggregate is
the reduced weight it provides, which results in a variety of implications;
because concrete made with LDA offers the same strength at a lesser weight, the
use of such concrete makes longer and slimmer spans of structural concrete
possible. This allows engineers to improve the overall design of the structure
and can even yield structures that would otherwise not be possible. Similarly,
structures with a lighter footprint can be located on soils that would
otherwise not be able to support such a structure.
A number of cost savings are also apparent when working with fly
ash LDA:
Lower Shipping & Handling Costs
A lighter weight concrete product can reduce shipping costs
because more units can be transported together, decreasing the number of
shipments needed. Similarly, handling costs may also be reduced as a result of
a lighter weight material.
Reduced Structural Costs
The use of concrete made with LDA also helps to reduce structural
costs; lighter-weight structural elements such as beams and footings can be
used, cutting down the cost of materials.
Reduced Disposal Costs
The beneficial reuse of fly ash reduces disposal costs for
producers and can even create an additional source of revenue.
ENVIRONMENTAL
BENEFITS
The beneficial reuse of fly ash offers a number of environmental
benefits as well:
Reduced Use of fossil fuel/Mined Resources
The use of fly ash as a lightweight aggregate reduces the need for
companies to mine natural aggregate materials for use in concrete production.
Reduced Pressure on Landfills
Landfilling has long been used as a primary approach to the
disposal of fly ash. But as landfills become increasingly unsustainable, the
ability to divert materials from landfill offers significant value.
Reduced Need for Coal Ash Ponds
Reuse reduces the need for containment ponds, where wet fly ash is released all over the surrounding
area with devastating consequences.
