Application:

  • BOYUAN SNF also allows concrete to be produced with very low water/cement ratios at low or normal slumps.
  • BOYUAN SNF is ideal for use in pre stress, precast, bridge deck or any concrete where it is desired to keep the water/cement ratio to a minimum and still achieve the degree of workability necessary to provide easy placement and consolidation.
  • BOYUAN SNF will also fluidize concrete, making it ideal for tremie concreting or other applications where high slumps are desired.application.jpg
