Application,

Water-reducing agent dosage is 0.20-0.30% of the cement, reducing the water rate is 9-11%, 0.25- mixed compared with the reference concrete 3 days strength increased by 20%, 7days increased 15-20%, 28 days increased by 15%, long-term strength has also increased.In the circumstances that cement content and water content using consistent with the reference concrete, can increase the collapsibility 2-4 timesIn maintaining the concrete collapsibility it can save 8-10% of cement, that is to save 30-40 tons using 1 ton of Sodium Lignosulphonate.In the standard state, may delay the initial setting time 2.5 hours of concrete and final setting time 3 hours, hydration heat peak delayed more than 5 hours and can be conducted to the summer construction, commercial concrete transportation and mass concrete works.Sodium Lignosulphonate can improve the concrete mature of impermeability, freezing and thawing.The agent have non-corrosion function after mixing of concrete.
