For Sodium lignin water reducer, recommended amount in the concrete cement (weight) of 0.2% 0.6%, the user should determine the optimal dosage through the experiment. Sodium lignosulfonate can be used as liquid.
The effect of Sodium lignosulphonate is significant when compound with naphthalene high-performance water reducer. the user should determine the optimal dosage through the experiment.
When using sodium lignin water reducer, must control the dosage strictly, effect will not obvious if less, it will affect the early strength of concrete. When the temperature is below 5 ℃, it is inappropriate used alone for concrete projects.
