Introduction
1. Sodium lignosulfonate is a kind of natural highmolecular polymer, it has good and different extent dispersibility owing to different molecular weight and functional group.
2. Sodium lignosulfonateis a kind of surface active material, also can fix on the surface of various solid particle, make interaction with every metal ion.
3. Sodium lignosulfonate can also make condensation function and hydrogen-bond interaction with other chemical compound because of the exist of different active group in their organization structure.
Advantage
1. Reduces the water content by 5-10%
2.Decreases the concrete porosity
3. Increases the concrete strength by up to 25% (as less water is required for the concrete mixture to remain workable)
4. Increases the workability (assuming the amount of free water remains constant)
5. Reduces the water permeability (due to less water being used)
6. Reduces the diffusivity of aggressive agents in the concrete and so improves the durability of concrete
7.Gives a better finish to surfaces (due to all of the above)
