ASTM C494 TYPES B & D CRD - C87 TYPES B & D; BS 5075 IS-9103-79
We at Perma constructions aid, are noted for Perma Retard, which is a liquid admixture for concrete based on refined Lingo sulphonates and Naphthalene formaldehyde blends. Our products helps in production of super plasticized and set retarded concrete to enable the delayed pouring of concrete after its production or to get over the problems arising during hot weather concreting. Being well known in that market, we can ensure that our Admixture for Cement-is of genuine quality that can be use for construction works.
To produce concrete with delayed initial and final setting times.
Use of Perma Retard in hot weather ensures continuous pours resulting in monolithic sound concrete. Improves ultimate strengths significantly. Helps saving in cements in rich mixes.
DIRECTIONS FOR USE
Perma Retard should be added to the concrete mix along with water in the desired dosage. Perma Retard should not be added to the dry mix.
Field Trials should be carried out with the given cement and aggregates to arrive at optimum dosages for the desired property to be achieved. However for guidance we specify a range of 0.3 to 0.9 percent by weight of cement.
