Conplast PA21 is a chloride-free air entraining admixture based on selected lignosulphonates and active agents.
Suitable to produce air entrained concrete for increased durability and resistance to damage by frost and deicing salts. Typical applications include concrete roads and bridge decks, airport runaways and other extensive areas of concrete exposed to potential frost damage.
To improve cohesion and workability of concrete mixes where poorly graded aggregates must be used and bleeding, segregation or sand runs occur.
To reduce permeability of lean concrete mixes.
To improve stability and cohesion in extruded concrete.
