Lignosulfonate function to construction admixture
Compressive strength The compression strength characterized using a manual device and a more sophisticated device showed different results even though the trend is similar (Fig. 7). Flexural strength results are better measurements and distinguishable when a more sensitive sensor is used at 3, 7, and 28 days.Compressive strength properties are similar to the flexural strength…

Lignin and Lignosulfonate
Lignosulfonates or sulfonated lignin are water-soluble anionic polyelectrolyte polymers: they are byproducts from the production of wood pulp using sulfite pulping. Most delignification in sulfite pulping involves acidic cleavage of ether bonds, which connect many of the constituents of lignin. The electrophilic carbocations produced during ether cleavage react with bisulfite ions (HSO3−) to give sulfonates.R-O-R’ + H+ → R+ + R’OHR+ + HSO3− → R-SO3H. The primary site for ether cleavage is the…

Lignosulfonate used in animal feed additives
Lignosulphonates are amorphous branched polymers of lignin, containing sulphonated covalently linked phenyl propane monomers, produced from the sulphite pulping of lignocellulosic biomasses. The calcium lignosulphonate, sodium lignosulphonate and magnesium lignosulphonate under assessment are considered together under the term lignosulphonate. Lignosulphonate is safe for chickens for fattening, laying hens, pigs forfattening and cattle for fattening at…

Lignosulfonate used in construction
Sodium lignosulfonates having perfect technical characteristics are commonly used in construction. The main advantage of this unique product is that it is eco-friendly for environment and human health, have high surface activity and stabilizing properties. Lignosulfonates are used for concrete, cement slurry and plaster blends manufacture, help to produce workable and flowable slurry and increasing…
