Import Calcium Lignosulphonate — Buy in Bulk from Supplier in China

Calcium lignosulphonate from Jinan Yuansheng Chemical Co., Ltd. is a water-soluble natural polymer derived from sustainable wood pulping byproducts. It serves as a dispersant and plasticizer in construction formulations, notably improving workability in concrete and cement mixes by reducing water demand without compromising strength. The product is supplied as a brown powder with high solubility, enabling uniform distribution in aqueous systems.

The additive functions as a set retarder and water reducer in concrete, extending working time while enhancing durability. Its lignosulphonate base provides inherent binding properties, making it suitable for adhesives, paints, and other industrial applications where cohesion and stability are critical. Typical industry use includes dosages of 0.2 to 0.5% by weight of cement, with performance validated under standard ASTM C494 for concrete admixtures.

Primary buyers include construction firms, concrete batching plants, and manufacturers of building materials who require consistent performance in large-scale projects.
