WINFLOW-SP[Ⅰ]
- High-liquidityconcrete
WINFLOW-SP[Ⅰ] is a high-liquidity concrete thatuses Naphthalene condensates plus Lignosulfonates asthe main ingredient. Concrete with poor workability is changed into a goodamount of workability without the differences in the amount of air, settingtime, and segregation of materials due to the dispersion effect on cementpaste. Especially, smooth constructability and easy workability ofhigh-liquidity concrete can be achieved by preventing the strength degradationcaused by adding water and the promotion of slump when placing concrete.
● USAGE
* High-qualityconcrete of general construction and civil engineering structures
* Whenmanufacturing high fluidity concrete
● DOSAGE
* Typicalratios of 0.3% to 1.0% byweight of cement are suggested. Please test concrete to make sure each batchmeets the exact specification on site.
* Afteradding it, the mixture is mixed for 2-3 minutes at the high-speed rotation andthen concrete is placed.
* Afteradding it 0.1% to concrete, an standard increase in slump is 2±0.5㎝.
* Excessivecement in concrete can lead to the decrease in bleeding, segregation, and theamount of air.
● ADVANTAGES
* Excellentworkability can be easy when the liquidity is enhanced.
* Thefinishing touch can be enhanced by reducing concrete bleeding.
* Itenhances the ability to pump.
* Theexcellent dispersion effect can be offered when mixing fly ash, slag, and silica fume.
* Increasedresistance to freeze and thaw cycles is provided
● PROPERTIES
* Appearance : Light brown liquid
* Specific gravity : 1.200±0.05(20℃)
* pH : 7.0±3.0
