High performance admixture and compaction aid for wet semidry/no-slump concrete products
Areas of Application
Duplast HP (VC) offers substantial benefits to the producer of wet, semi-dry/no slump
Efficient dispersion and distribution of cement, additives and pigments Give high early strength to wet concrete Improved movement of the concrete through the machine (faster mould filling) Optimized compaction with shorter pressing time and increased output [ shorter production cycle ] Minimized friction between the mould and the concrete [ Reductions in equipment wear and tear ] Reduced adhesion/stickiness between top layer concrete and pressing head/tamper (equipment/tools) Increased “green” strength on immediate de-moulding [ keeps the shape of freshly de-moulded semi-dry concrete products because it prevents slumping after demoulding
] More economic concrete mix designs Create superior products
Duplast HP (VC) allows for the following advantages in the finished concrete products:
Duplast HP (VC) conforms to IS 9103-1999
In general a mixing time of at least 30 seconds is essential, although the actual mixing time after adding the admixture depends on the individual circumstances and should be determined by trials.
NOTES ON APPLICATION /LIMITATION
Duplast HP (VC) can be added with the mixing water or introduced at the end of the mixing process. Duplast HP (VC) must not be used for wet cast concrete as this could result in excessive air entrainment and subsequent loss of strength. Before use suitability tests must be performed.
15 months from date of production if stored properly in undamaged unopened, original sealed packaging in dry conditions at temperatures between +5°C and +40°C. Protect from direct sunlight and frost.
