PH acidity sodium lignosulfonate concrete admixture industrial chemical products

The technical indicators of PH acidity sodium lignosulfonate concrete admixture as follows :

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 ℃.
