Product Overview

Key Features

High Range Water Reducing Superplasticizer

KR AA 20 is high range water reducing admixture. It may be added to the job site or at the ready mix concrete plant. It is chlorides free. It is recommended for prestressed concrete. It is also very compatible with air entraining agents, water proofing agent and many other admixtures; however, each material should be added to the concrete separately.

PRIMARY APPLICATION

High performance concrete
Paver /Block Industries,
Heavily reinforced concrete
Flatwork and mass concrete
Low water /cement ratio concrete
High slump, flowable concrete

FEATURES/BENEFITS

Produces low water content and low water /cement ratio concrete allowing higher strengths
Produces flowing concrete with better than normal strengths
Aids in concrete placement and reduces labor cost
When used in precast, produce the high early strengths.

SPECFICATIONS/COMPLIANCES complies with the requirements of ASTM C-494, Type A & F admixtures. Confirming to IS 9103.

PACKAGING KR AA 20 in 100-250 kg.

Shelf life: 1 year in original, unopened packages.

Concrete treated with KR AA 20 retains its plastic consistency for 30 to 60 minutes after Dosing depending on the initial/final slumps and dosage rates. KR AA 20 can be added at the ready mix plant or at the job site from field dispensers. Use KR AA 20 When placing concrete in hot weather >35 C.

Initial Slump	Collapse
Slump after 30 min.	170-180 mm
Slump after 60 min.	150-160 mm.
Slump after 120 min.	90 - 120 mm

( Product performance depend on actual site condition and differ from site to site. Need to conduct site trials to fix up the actual dosages.)

Appearance
KR AA 20 is a dark brown, free flowing liquid When added to concrete, does not Change the Concretes natural appearance.

DIRECTIONS FOR USE
KR AA 20 add to The water .it should not come into contact with dry cement.

High strength Concrete Dosage-
Add all concrete materials in the proper order into the mixer with about 70% of the mixing water and mix 1-2 minutes. Add additional water carefully to obtain the required slump and mix for three (3) Use KR AA 20 at the rate of 0.4 -1.2%by weight of cement and at extremely high temperature dosages can be increase up to 2.2%. even with low water/cement ratio.

Placeable Concrete
Add all concrete material in the proper Order into the mixer and mix 2-3 minutes for to get required slump. Add KR AA 20 and mix an additional One minute.

Flowable concrete

Add all concrete material in the proper Order into the mixer and mix 2-3minutes. Add KR AA 20 and mix an additional two minutes. For flowable concrete and high slump concrete dosage can be use up to 1.2% -1.5% by weight of cement.
Placement Concrete treated with KR AA 20 maybe placed in the fashion as conventional concrete.

Formwork
Forms for walls or narrow sections must be water tight, strong and have good bracing. During the "flowing period", when the concrete is at a slump of 7" to 9" (178- 220 mm)the concrete will exert a higher pressure at the base of the form then conventional concrete. Formwork for slabs is the same as for conventional concrete. Curing & sealing proper curing procedures are important to ensure the durability and quality of concrete. To prevent surface cracking cure flatwork with a high solids curing compound.

PRECAUTIONS /LIMITATIONS

Care should be taken to maintain KR AA 20 above freezing, however, freezing and subsequent thawing will not harm the material if thoroughly agitated. Never agitate with air or an air lance.
Test batches/mix designs /sample slabs may be required due to variations in local cement and aggregates.
KR AA 20 is used in many different mix designs. The engineering or Technical services Departments of the Cmix India Company should be consulted whenever a question on usage or compability with other admixtures is raised.
