Hyperplast
PC218

HIGH RANGE WATER REDUCING ADMIXTURE BASED ON POLYCARBOXYLATE POLYMERS

Advantages:

Optimizes cement utilization
Improves the water impermeability characteristics of concrete mix
Significantly improves the slump retention characteristic without affecting the setting time
Increases the durability and resistance to aggressive atmospheric conditions
Significantly improves early and ultimate compressive strengths
Minimizes segregation and bleeding problems by improving the cohesion of concrete mixes

Description:

Hyperplast PC218 is a high range water reducing admixture based on polycarboxylic polymers with selective additives which are especially formulated to enable the water content of the concrete to perform in a more effective manner.

This effect can be used in different concrete applications where it is required to keep the water-to-cement ratio at a minimum level while maintaining an excellent workability and strength performance.

Usage

Acts as a high range water reducer for the production of high strength and high performance concrete
Suitable for normal weight and light weight concrete in ready-mix, precast and pre-stressed applications
Production of self-levelling concrete
Improves the cohesion of concrete for use in mass concrete pours and piling
Structures with congested reinforcement

Materials Supplied

Hyperplast PC218 is available in 275 gal (1,041 litre) and 330 gal (1,249 litre) IBC totes. Bulk supply in tanker trucks is also available upon request.

Shelf Life

Hyperplast PC218 has a shelf life of 12 months from date of manufacture if stored at temperatures between 35˚F and 122˚F (2°C and 50°C).

Application Instructions

Hyperplast PC218 should be added to the concrete with the mixing water to achieve optimum performance.

An automatic dispenser should be used to dispense the correct quantity of Hyperplast PC218 to the concrete mix.

DOSAGE

The recommended dosage of Hyperplast PC218 is 7 to 20 fl oz/100 Ib (455 -1300 ml/100 kg) of cement or cementitious materials in the mix including GGBFS, PFA or micro-silica.

Representative trials should be first conducted to determine the optimum dosage of Hyperplast PC218 to meet the performance requirements by using the materials and conditions in actual use.

EFFECTS OF OVER DOSAGE

Overdosage of Hyperplast PC218 will cause the following:

- Significant increase in retardation.
- Increase in workability.

Ultimate concrete strength will not be adversely affected and will generally be increased provided that proper concrete curing is maintained.

HEALTH AND SAFETY

Consult the appropriate Material Safety Data sheet prior to using Hyperplast PC218.
