QUANTEC® PL-422 is a low dosage, higher performance plasticisier acting in conjunction with a catalyst, to produce a synergistically effect low in slump mixes which improves both cement dispersion (optimising hydration potential) and strength gain characteristics. Particular benefits can be found in machine-made masonry pro ducts, brick, block and paver production.
QUANTEC® PL-422 is intended for use in block mix concretes, and low slump concrete systems involving vibro-compression and instant de-moulding.
QUANTEC® PL-422 is manufactured under carefully controlled conditions, to produce a highly consistent product.
| Appearance | Dark amber liquid |
| Specific Gravity (20°C) | 1.13 |
| Air Entrainment | None in semi-dry mixes |
| Freezing Point | 0ºC |
QUANTEC® PL-422 is supplied ready for use and should be added to the mix after the addition of the cementitious component, at the same time as the mixing water.
Overdosing in semi-dry mixes will yield a more plastic mixture, and problems may be experienced with edge slumping of cast masonry units and retardation of set and strength development.
The set retardation effect will depend on ambient temperatures, cement used and amount overdosed. However, if the units are properly cured, the ultimate strength will generally be higher than normal.
| Range | 150 ml - 300 ml per 100 kg cement |
| For best results, it is recommended that QUANTEC® PL-422 performance first be assessed in preliminary tests using the actual mix constituents. This will help determine the optimum dosage. | |
| For advice and assistance with trials we recommend that you consult GCP Applied Technologies. | |
QUANTEC® PL-422 can be used with all types of Portland cement, including cement replacement materials.
For use with special cements we recommend that you consult GCP Applied Technologies.
QUANTEC® PL-422 should not be pre-mixed with other admixtures prior to addition to the mix.
The performance of the admixture may be affected by the presence of other chemicals, and we recommend that GCP be consulted in such circumstances.
It is preferable that liquid admixtures for concrete should be introduced into the mixer by means of automatic dispensing equipment.
