Description:
Product Introduction
Sodium Lignosulphonate ( lignosulfonate )concrete water reducer (HMJ) is mainly for concrete
admixture as water-reducing additive. It is low dosage , low air content .The water reducing rate is
high. It adapts to most kinds of cement. It can be confected as early age strength enhancer for

concrete , concrete retarder , antifreeze , pumping aids etc. There is nearly no precipitated product

in the liquid additive which is made from the sodium lignosulphonate and Naphthalin-Group high-

efficiency water reducer . It can lower the mixed water requirements, promote the workability of

concrete admixtures and reduce formulation cost, The sodium lignosulphonate is fit for building

project, dam project, thruway project etc. It is the economical one.

Inspection Report

1,It can reduce 10% of water consumption at least;
2,It can improve mixture of the concrete;
3,There will be improvement for compression strength by more than 15% equally in 3-28 days;
4,It can reduce the heat of hydration in initial stage of the cement by a large margin;
5,There is no corrosion on the concrete reinforcing bar.
Operation Method
1,When 0.2-0.5% of mixing amount is in concrete (with cement weight), users can adjust the mixing
amount through the test.
2,It can be used after mixing liquid, also can be put with cement , aggregated into mixer to use at
the same time also. The time is needed to be lengthened properly.
3,The result is more obvious after mixing with Naphthalin-Group high-efficiency water reducer . User
can determine the suitable dosage according to the result that cement variety, aggregated
situation, Naphthalin-Group high-efficiency water reducer are tested fixing.
Notice
1,Strict control is required to avoid excessive dosage;
2,When the temperature is lower under 5 C °, common concrete projects are not suitable to use the
chemical additive independently.
3,Experiment is required to make sure the dosage before use.
