Ⅰ, 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.

Ⅲ, Inspection Report
 

Ⅳ, Main Performance

  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.
 
Ⅴ, 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.
 
Ⅵ, 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.
 
Ⅶ, Packaging , Storage and Transportation
 
  Packing :There is plastic pellicle inside and is exteriorly packed with plastic woven bag with 25kgs as
  net weight per bag.

  Storage :It shall be stored in a waterproof, rainproof place to avoid agglomeration. If there is
  agglomeration, smashing it or dissolving it will not affect the using effect.The product is harmless and
  does not deteriorate in long term storage. It's not a flammable and explosive substance.

  Transportation : There will be no hooks when loading or unloading. It's suitable for both truck
  transportation and railway transportaion without any limit of sundries traffic or containerized traffic.
