Calcium lignosulfonate (referred to as wood calcium), the main component of the sulphate wood pulp waste liquid, is a yellow powdery solid processed by advanced production technology, which is easily dissolved in water. It is a polymer electrolyte whose molecular weight ranges from 1,000 to 100,000. Among them, the dispersibility of 10,000-40000 is particularly effective. The ordinary lignosulfonate has a branched and cross-linked molecular structure. It has strong dispersibility, adhesion and chelation. Our company's calcium lignosulfonate is widely used as cement water reducer, pesticide suspension agent, ceramic body enhancer, coal water slurry dispersant, leather tanning Agent, refractory binder, carbon black granulating agent, water treatment agent, etc.

Calcium Lignosulfonate Concrete Water Reducer Application:


Calcium lignosulfonate and sodium lignosulfonate water-reducing agent are a kind of surface active agent. After being added to concrete, the water-repellent group is directionally adsorbed on the surface of cement particles, so that the cement has a negative charge. Cement particles with the same electric charge repel and disperse each other under the action of charge repulsion. The flocculent structure formed by the cement at the initial stage of adding water becomes a dispersed structure, and the free water in the flocculated aggregate is released, thereby achieving the purpose of a water reducing agent.

Observations show that after the wood calcium is added to the concrete, more than 80% of the water reducing agent has been adsorbed after mixing for 5 minutes. The center of the hydration point clearly visible under the electron microscope is obviously increased, the hydrate is uniformly distributed, and the hydrated crystal fiber is longer. Various micro characteristics. It can be seen that by adding calcium lignosulfonate, there are fewer pores left by the evaporation of free water, and the internal structure is compact.


That is to say, the reduction of porosity is obviously conducive to the improvement of concrete strength, and the size and distribution of the pore structure of cement are improved. Under the circumstances, the crystal growth rate is delayed and the crystal growth is more complete, so more fibrous crystals are interspersed with each other to form a strong network structure, thereby significantly improving the strength of the concrete.

Therefore, the use of wood calcium water-reducing agent in concrete can reduce the water consumption of the concrete mixture, reduce the water-cement ratio, improve workability, facilitate pumping, and improve concrete strength, compactness and durability.
