POLYTANCRETE - SPRSLUMP RETAINING, RETARDING SUPERPLASTCIZER

DESCRIPTION POLYTANCRETE - SPR is specially formulated admixture based on sulfonated napthalene 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 minimise 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 trials and design mix please contact our CONCRETE MATERIAL CONSULTANCY DIVISION ( CMCD ).
