Chemicals used in cement industry Naphthalene Sulfonate Formaldehyde SNF exporters
Usage
- SNF produces concrete with extremely workable characteristics referred to as high slump.
- SNF also allows concrete to be produced with very low water/cement ratios at low or normal slumps.
- 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.
- SNF will also fluidize concrete, making it ideal for tremie concreting or other applications where high slumps are desired.
- SNF is compatible with Portland Cement, Normal Portland cement, Portland Slag Cement, Fly-ash Cement, Portland Pozzolanic Cement, etc.
Properties
- Visual Appearance: Light brown powder. Non-poisonous, odorless, non-flammable and non-corrosive to steel bars.
- Remarkable Plasticity: As a condition of blending where amount of cement and collapsibility are fixed aforehand, mixing water can be decreased by 10-30% when it is mixed with reinforced concrete at 0.3-1.5%.
- Improve miscibility of concrete amalgamator with water and collapsibility as well. As a condition of equivalent blending, collapsibility can be increased.
