Liquid lignin can be used as a water reducing agent in concrete with a water reducing rate of 8-9%. It can also be used as retarding agent, early strength agent, air entraining agent, road dust removal agent, mineral binder, pumping agent and cement abrasive.
| In the appropriate dosage, the water reduction rate can reach 9-11%, improve the strength of concrete 15-20%, 3-day, 7-day strength increases 20-30%, 28-day strength increases 15-20%, long-term strength also increases. |
| In the case of the same water content of concrete, it can enhance the fluidity and workability of concrete. |
| Under the condition of keeping the slump and strength of concrete unchanged, it can save 8%-10% cement. |
| The initial setting time of concrete can be extended by more than 3 hours, the final setting time can be extended by 3 hours, and the peak hydration heat delay is 5 hours. Suitable for summer construction, commercial concrete transportation and mass concrete projects. |
| This product has air inlet function, can improve the permeability of concrete freeze-thaw performance. |
| No corrosion to steel and aggregate. |
