Description
POLYTANCRETE - SPR is specially formulated admixture based on sulfonated naphthalene polymer modified carbohydrates. It is supplied as dark brown colored liquid miscible with water.
Conformance
Confirms to IS: 9103:1999 and ASTM – C 494M – 99a, 1999 Type G as slump retaining, retarding superplasticizer.
Salient Features
- Increased workability at reduced water.
- Flowing yet very cohesive concrete is produced which can easily be pumped.
- High early strength due to high water reduction.
- Due to increased workability, placing and compaction is easier.
- Chloride free
- Resultant savings in time and cost.
Applications
- High Performance concrete
- Workability retention concrete
- Safe for use in prestressed and reinforced concrete.
- Hot weather concreting where rapid slump loss occurs.
Directions for use
POLYTANCRETE - SPR is added to prewetted concrete mix at a rate of 0.5 to 0.7 Lt. per bag of cement.However actual site trials have to be carried out to minimize the optimum dose for the intended application. The measured quantity of POLYTANCRETE – SPR is mixed with part of guaging water and then added to the mix. For further assistance in optimum dosage trialsand design mix please contact our CONCRETE MATERIAL CONSULTANCY DIVISION ( CMCD ).
Compatibility
Compatible with all types of cement It is also compatible with other SUNANDA’S CONCRETE ADMIXTURES, but should be added separately.
