Sodium Lignosulphonate (SLS) Concrete Water Reducer
The technical indicators of Sodium lignosulphonate retarder concrete admixture as follows :
Product Name: Sodium Lignosulphonate Concrete Water Reducer
Item | Index |
Moisture content (%) | ≤7 |
PH value | 7-9.5 |
Reducing sugar content (%) | ≤8 |
Water-insoluble (%) | ≤0.3 |
Sulphate content (%) | ≤6 |
Usage :
The recommended volume of Sodium lignosulfonate water reducer in the concrete : 0.2%-0.6%
(cement weight), the user should determine the optimal dosage by experiment. And the sodium
lignosulfonate could be used by prepared into liquid.
Sodium lignosulfonate water reducer has obvious effect when compounded with naphthalene
superplasticizer.The experiments can be performed to determine the dosage and proportion for
users.
Note:
Control the volume strictly when using the sodium lignosulfonate water reducer, the effect is not
obvious if less and influence the early strength of concrete if more. It should not be used in the generalconcrete engineering alone when the temperature is below 5 ℃.
Advantages
1.Used for concrete water reducer: it’s a powdery low air-entraining retarding superplasticizer,
and belongs to anionic surfactant, has adsorption and dispersion effect on cement, above all, it can
improve the various physical properties of concrete.It reduces water above 13%, improves the
workability of concrete,and could be compounded into early strength agent, retarder, antifreeze,
pumping agent etc.The liquid additive compounded with naphthalene superplasticizer basically has
no precipitate.
2.Used for coal water slurry additive.Add this product in the process of preparing coal water slurry,
can increase production of the mill, keep the making system in normal and reduce it’s power
consumption, so that improve the concentration of coal water slurry.
3.Used for fireproofing materials and ceramic body reinforcing agent.In the manufacturing process of large size tiles and refractory brick, it make the blank body raw material particles bonded together
firmly, and increased the dry strength more than 20%-60%.
4.As the dilution and dispersion agent, viscosity reducer in drilling; improving the liquidity in pipeline
transportation of crude oil and reducing the energy consumption.In the crude oil products, as a
cleaning agent, dispersing agent, high alkaline additives, anti rust agent, antistatic agent, emulsifying viscosity reducer, Eliminating wax and paraffin inhibitor etc.
