High Performance concrete superplasticiser, based on polycarboxylic technology
PROCRETE R75 differentiated from conventional superplasticisers in that it is based on a unique carboxylic ether polymer with long lateral chains. This greatly improves cement dispersion. At the start of the mixing process an electrostatic dispersion occurs but the cement particleÃƒÂ¢Ã‚Â€Ã‚Â™s capacity to separate and disperse.This mechanism considerably reduces the water demand in flowable concrete.
PROCRETE R75 combines properties of water reduction and workability retention. It allows the production of high performance concrete and/or concrete with high workability.
PROCRETE R75 is a particularly strong super-plasticiser allowing production of consistent concrete properties around the required dosage.
PROCRETE R75 is a high performance super- plasticizer intended for applications where increased early and ultimate compressive strengths are required, and it has been developed for use in:
Self compacting concrete
Concrete requiring long workability retention
High performance concrete
Increased early and ultimate compressive strengths
Increased flexural strength
Higher E modulus
Improved adhesion to reinforcing and prestressing steel
Better resistance to carbonation Lower permeability
Better resistance to aggressive atmospheric condition
Reduced shrinkage and creep

The optimum dosage of PROCRETE R75 to meet specific requirements should be determined by trials using the materials and conditions that will be experienced in use.
The normal dosage range is between 0.3 to 2.5 kg /100 kg of cementitious material.
Use at Other Dosages:
Dosage outside the normal range quoted above can be used to meet particular mix requirements. Contact REDWOP for advice in these cases
Effects Of Overdosing:
Over dosage may cause delay in the setting time.
PROCRETE R75 has a shelf life of 24 months provided the temperature is kept within the range of 5oC to 50oC.
Should the temperature of the product fall outside this range then contact local REDWOP office for advice.
