calcium lignosulfonate

Calcium lignosulfonate belongs to the class of organic compounds known as lignans, neolignans and related compounds. These are plant products of low molecular weight formed primarily from oxidative coupling of two p-propylphenol moieties.

They can also be described as micromolecules with two phenylpropanoid units coupled together. They can be attached in various manners, like C5-C5′, C8-C8′. Most known natural lignans are oxidized at C9 and C9´ and, based upon the way in which oxygen is incorporated into the skeleton and on the cyclization patterns, a wide range of lignans of very different structural types can be formed. Calcium lignosulfonate is an extremely weak basic (essentially neutral) compound (based on its pKa). Calcium lignosulfonate is an odorless tasting compound.

Performance and use

1. The use level of product is 0.20-0.30% of cement dosage, common dosage of 0.25%, reducing the water rates up to 8-12%.

2. Does not change dosage the water , it can increase the mobility of concrete to improve workability.

3 .While maintaining concrete slump, with the same intensity and the reference concrete, can save 8-10% of cement.

4.Calcium lignosulfonate superplasticizer with mic4.ro-cited gas can increase the impermeability of concrete freeze-thaw performance.

5. This product is not corrosive to the steel reinforcement and aggregate.This product is suitable for large volume concrete, high fluidity concrete, pumping concrete, commercial concrete, and concrete construction in summer, and there are special requirements for slow setting concrete, piles of concrete, Shen pile of concrete, hand-dug hole large volume of concrete and underground concrete construction, generally with the use of superplasticizer compound.
