FARCOPLAST PR

Applications

• Tremie concrete
• Hot weather concreting
• Suitable for cements with high slump losses
• Concrete containing fly ash or silica fume
• Blast furnace slag cement concrete
• Pumping concrete

Advantages

• Provides a cohesive non segregating concrete mixture
• Concretes with slump retention properties of 2 to 6 hours Improves impermeability against sulfate, chloride

and water due to reduced water content

• Improves abrasion and frost resistance by decreasing W/CM
• PR is specially suitable for producing high workability concrete that has excellent workability retention, in this application, extension in setting time and little loss in early age compressive strength are observed.
• Reduced dosage range in comparison with conventional polycarboxylates.

Method of use

• FARCOPLAST PRis supplied ready for use and is completely miscible in water.
• It can be added in to the mixer at the same time as the mixing water.
• It should not be added directly to the cement or dry materials.
• FARCOPLAST PR may be added at the end of mixing process by dispensing equipment or it may also be added to the concrete in a drum of ready mix truck, it should be mixed at least 1 minute per m³ of concrete at high speed.

Dosage

• PR is normally dosed at a rate of 0.5-1.4% by weight of cementitious materials weight.

• Dosage recommendations depend on the characteristics of the mix design.
• Field testing is recommended to determine the optimum dosage and effect on both plastic and hardened concrete properties such as : workability and workability retention, setting time, early and ultimate strength.
