Product Description
Calcium lignosulfonate is a brown powder with good water solubility. Calcium lignosulfonate is a derivative of lignin. In recent years, its modification to prepare surfactants has developed vigorously and made a series of important progress.
Application
Concrete water reducing agent calcium lignosulfonate used as concrete water reducing agent has adsorption and dispersion effect on cement, and can improve various physical properties of concrete. After being added to concrete, the hydrophobic group is directively adsorbed on the surface of the cement particles, so that the cement has a negative Chemicalbook charge. The cement particles with the same charge are repulsive and disperse each other under the action of charge repulsion, and the flocculent structure formed in the initial stage of cement water addition becomes a dispersive structure, and the free water in the flocculating condensate is released, so as to achieve the purpose of water reducing agent.
Calcium lignosulfonate superplasticizer is suitable for large volume concrete, large flow concrete, pumped concrete, commercial concrete and summer concrete construction as well as concrete with special Chemicalbook requirements for slow setting, cast-in pile concrete, sunk pipe pile concrete, artificial dug concrete and underground mass concrete construction, generally combined with high efficiency superplasticizer.
