Sodium lignosulfonate used as plasticizer in concrete will reduce the cost by 10-15%,the sodium lignosulfonate could assume 0.5-2% of the total mixture w/w,will increase the strength of concrete by 20-26%.
Sodium Lignosulfonate plasticizer Functions as follows
Improved strength and durability of the cured concrete
Reduced formulation cost
Increased workability of the concrete mix
Sodium lignosulfonate uses water reducing agent, By sulfite pulp waste liquid of legal system formed by chemical modification and processing. Medium molecular weight, The reducing sugar content in low,Used for concrete admixture, With low dosage, low gas content, to cement the characteristics of strong adaptability, The most notable feature is the rear with naphthalene superplasticizer complex, Liquid admixture made no precipitate.
Main performance
Can reduce water consumption by more than 14%, Significantly improve the workability of concrete. Can greatly reduce the initial heat of hydration of cement hydration. No chlorine salt, no corrosive effect on steel. Alkali-free active substance.
1.Sodium Lignosulfonate uses as superplasticizer dosage of cement content 0.20-0.30%, commonly used dosage is 0.25% water reduction of up to 9-11%. In the appropriate dosage when compared with the reference concrete strength increased by 15-20% 3 days, 7 days strength increased 20-30%, 28 days by 15-20%, long-term strength also increased.
2.Without changing the water in the case of concrete( suggested ratio 0.65)1to increase the flow of concrete, improved work-ability.
3.In keeping concrete slump, the same intensity and the reference concrete, cement can save 8-10%, the use of one ton of Lignosulfonate superplasticizer powder, can save 30-40 tons of cement.
Method of use
Sodium lignosulfonate uses as water reducing agent,In concrete recommended dosage of 0.2% -0.6%(cement weight meter), Users should determine the optimal dosage through the experiment. Sodium lignosulfonate water reducing agent can be used as liquid. Users can experiment to determine the content and proportion.
Note
Using sodium lignosulfonate water reducing agent, Strictly control the content,use less the effect is not obvious,use more affect the early strength of concrete. When the temperature is below 5 ℃, Concrete works should not be used alone.
