Set-Control Additives-Plastit® R

Plastit R is a water solution of active polymers that retard cement hydration and limit slump loss in concrete and cementitious materials during hot weather and when transporting over long distances

Set retardation allows extra placing time for larger pours
 Set retardation controls stiffening time of concrete and cementitious materials in hot weather
 Long distance transportation of concrete

Provides retardation in initial and final setting time in all cementitious materials

The optimum dosage Plastit R to meet specific requirements should always be determined by trials using the materials and conditions that will be experienced in use. The normal dosage range is 0.4 to 1.2 kg/100 kg of cementitious material, including PFA, GGBFS and microsilica
