Product Code : PROCRETE NPL S15
Brand Name : Redwop
Product Description

PC based water reducer admixture

Uses

To produce lower and medium grade concrete To produce pumpable concrete To produce high strength, high grade concrete by substantial reduction in water resulting in low permeability and high early strength. To produce high workability concrete requiring little or no vibration during placing.


Advantages

Improved workability - Easier, quicker placing and

compaction.

Increased strength - Provides high early strength concrete and with reduced water contents precast concrete.

Improved quality  High Durability due Denser, close textured concrete with reduced porosity.

Higher cohesion - Risk of segregation and bleeding minimized; thus aids pumping of concrete

Chloride free - Safe in pre stressed concrete and with sulphate resisting cements and marine aggregates.


Standards

Procrete NPL-S-15 complies with IS: 9103:1999 and BS 5075-Part 3 and ASTM-C-494 Type 'G'

Description

Procrete NPL-S-15 based on PCE base Polymers and is supplied as a brown liquid instantly dispersible in water. Procrete NPL-S-15 has been specially formulated to give High water reductions without loss of workability or to produce high quality concrete of reduced permeability.


Properties

Specific gravity Approx. 1.00 at 27oC

pH at 27oC 6.0 - 8.0

Chloride content Nil to BS: 5075


Compatibility:

Can be used with all types of cements except high alumina cement. Procrete NPL-S-15 compatible with other types of REDWOP admixtures when added separately to the mix. Site trials should be carried out to optimize dosages.


Cohesion:

Cohesion is improved due to dispersion of cement particles thus minimizing segregation and improving surface finish.


Compressive strength:

Early strength is increased up to 40 to 50% if water reduction is taken advantage of. Generally, there is improvement in strength up to 20% depending upon W/C ratio and other mix parameters.


Durability:

Reduction in W/C ratio enables increase in density and impermeability thus enhancing durability of concrete.


Application instructions Dosage

Trials need to be carried out at site to determine the exact dosage of the admixture for the particular mix design and materials. However for normal grades of concrete a dosage from 0.4% - 1.0 % by weight of cement is recommended, the dosage may be increased to 1.5% to achieve specific slump requirements. For microsilica concrete where a high amount of water reduction and slump retention are required, trials need to be carried out to arrive at the correct dosage, as the dosage may increase up to 2.0% or even up to 2.5% by weight of cement depending on mix design and performance required.


Use at other dosages

Dosages outside the typical ranges quoted above can be used to meet particular requirements. Contact REDWOP Technical cell for advice

Over dosage

An overdose of above the recommended level of admixture may result in high workability, slight increase in air entrainment and retardation of setting time. The ultimate strength of the concrete will not be adversely affected and will generally be higher than for normal concrete if properly placed and cured.


Dispensing

The measured quantity of Procrete NPL-S-15 should addalong with the gauging water. For best results, add Procrete PC 5 in the last phase after pre-wetting the mix with 80% of the total water required.


Mix design

REDWOP has an advisory service on Concrete Mix Design and can be contacted if assistance is required.

Estimating Packing

Procrete NPL-S-15 is supplied in 200 Kg drums.


Storage

Procrete NPL-S-15 has a minimum shelf life of 12 months when stored under normal temperatures. It should be protected from extreme temperatures and preferably stored in shade. If kept for longer times please shake the contents well before use.


Precautions Health & Safety

Procrete NPL-S-15 is non-toxic. Any splashes on the skin should be washed immediately with water. Splashes to the eyes should be washed immediately with water and medical advice should be sought.


Fire

Procrete NPL-S-15 is non flammable.
