Retarding Admixtures is a liquid admixture for concrete based on refined Ligno sulphonate sand Naphthalene formaldehyde blends. Retarding Admixtures helps in production of super plasticised 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.
Primary Uses : To produce concrete with delayed Initial and final setting times.
Advantages : Use of Retarding Admixtures in hot weather ensures continuous pours resulting in monolithic sound concrete. Improves ultimate strengths significantly. Helps saving in cements in rich mixes.
