New generation, multi-dose,water reducing plasticiser
CHRYSO® Plast Omega 174 is classified as a water reducing plasticiser according to SANS 50934-2 (EN 934-2) Table 2. The admixture thus induces the following major effects in a concrete mix:

Without affecting the consistence (workability), permits a reduction in the water content of a given concrete or
Without affecting the water content, increases the slump/flow or
Produces both of the above effects simultaneously.

CHRYSO®Plast Omega 174 is a multi-dose admixture, allowing a wide range of dosages to be applied, without any excessive retardation at the higher dosages.
The multi-dose characteristic of CHRYSO®Plast Omega 174 allows concrete to exhibit extended workability characteristics.
When used to reduce the water content of a concrete mix (lower the w/b ratio) CHRYSO®Plast Omega 174 may potentially reduce the rate of bleeding.
CHRYSO®Plast Omega 174 improves the cohesion and lowers the viscosity of a concrete mix. This results in an improved homogeneity and compaction, allowing for superior off-shutter finishes.
By reducing the need to add extra water, CHRYSO®Plast Omega 174 increases the durability of concrete, by reducing permeability.
CHRYSO®Plast Omega 174 is robust to differences in cement characteristics. Based on aesthetic requirements, its suitability for use with white cement, should be ascertained prior to use.
CHRYSO®Plast Omega 174 may be used with in mixes extended with limestone and/or typically used SCMs – GGBS, GGCS, Fly Ash and Silica Fume.
CHRYSO®Plast Omega 174 does not undermine the early age strength of concrete and in certain cases, may be used to improve it.
Depending on the dosage, CHRYSO®Plast Omega 174 will cause a relative increase of mechanical strength after 24 hours.
