POLYTANCRET NGT
This is a liquid polymeric
admixture, useful for increasing the strength of concrete or mortar. It is also
useful for modifying and improving several properties of fresh or hardened
concrete.
The economics of concrete
production is governed primarily by the selection of right materials, although
construction costs do count in totality. The levels of design sophistication
reached to-day, do not allow any scope to reduce material consumption and
costs. Hence further savings can now be effected mostly by improving the
quality and strength of materials used in construction. Durability is a major
issue today which also needs to be addressed. Accordingly concrete of high strength
& durability has been developed by using new materials such as polymers,
various fibres, etc.
Use
POLYTANCRET NGT is recommended
for use in all concrete produced related to building and civil engineering
construction: prestressed concrete, precast concrete, waterproofing plaster,
free flowing concrete or mortar and pumpable concrete mixes etc.
Testing Standards
· Tests for compressive strength and other
concrete parameters show considerable improvement in properties.
·
A.S.T.M. C-494 Type F Confirms to the
requirement.
Advantages
Use of the prescribed
quantities of POLYTANCRET NGT considerably improves several properties of
concrete:
In Plastic Concrete
|
In Hardened Concrete
|
Improves Finishability
|
Increases all strengths
|
Improves Workability
|
Improve finished appearance
|
Reduces Water requirements
|
Reduces cracking
|
Reduces Segregation
|
Reduces permeability
|
POLYTANCRET NGT reduces the
water/cement ratio considerably while maintaining the workability. Hence calculate
the gauging water, by 10% to 20% volume reduction. It is desirable to have
trial mixes to assess the actual effect of the ingredients under field
conditions.
Instruction for use
POLYTANCRET NGT is water
soluble and is to be added to the gauging water (water to be mixed in the
concrete/mortar). Add 100 ml to 400 ml per bag (50 kg ) of cement or as per
requirements of slump or workability.
Packing
20 litre, 210 litre
Shelf life
Twelve months when stored in
original closed container.
