NIROSET RP is a high performance retarding plasticizer based on selected hydroxycarboxylic materials, beneficial in maintaining workability especially in high ambient temperatures. It is supplied as a colourless to brownish solution which instantly disperses in water.

NIROSET RP disperses in the concrete mix, enabling the water content of the concrete to perform more effectively. The initial hydration of the cement is also delayed, resulting in high workability retention of the concrete with no adverse effect on strength gain.
