Description
JK-07SLS is a spraydriedfermented sodium lignosulphonate derived spruce wood sulphiteliquor. It is a kind of natural anionic surface active agentprocessed with sulfurous acid pulping waste through advancedproduction technology. It is an aqueous solution of modifiedlignosulfonates containing a catalyst which promotes more completehydration of portland cement. It does not contain calciumchloride.
Uses
- The dosage is0.3-0.4%.
- It makes a workable mix and yields a stronger, less permeableand more durable concrete. It is used in ready mix plants, job siteplants and concrete pavers, for normal weight and light weightconcrete, in block, precast and prestressed concrete plants.
- As a dispersing agent, it lessens the natural interparticleattraction between cement grains in water. It does this bycolloidal action, by adsorption on the cement particles thusreducing their tendency to clump together and makes the mix moreworkable with less water.
- As a cement catalyst, it effects a more complete hydration ofthe cement, beginning immediately after the cement and water cometogether at the lower additions of it or immediately after a periodof designed and controlled hydration at the higher additions. Itincreases the gel content of the concrete, the paste or binder that"glues" the concrete aggregates together. The increased gel contentadds to the water retention and internal cohesiveness of the mix,reducing bleeding and segregation as it increases workability andplaceability
- This product is mainly used in all kinds of concrete placing insite,preformed concrete, reinforced concrete and prestressed concrete, especiallyapplicable for commercial concrete, anti-freezing concrete,waterproof concrete, bulk concrete, pumping concrete and soon.
