Use of lignin-based products in concrete - ScienceDirect
1996.1.1 Lignosulphonates are used as adhesive for plywood and particle board. Lignins find use in ceramics, carbon black, dyes, pigments and many other products. Lignosulphonates are also used as dispersants and foaming agents in the manufacture

2021.9.30 Initially, lignosulfonates were used as concrete admixtures because of the possibility of direct application, as well as the fact that a positive impact on the composite could be obtained without any additional chemical treatments.

2019.9.30 Approximately half of the lignin-derived products manufactured worldwide are used for production of cement and concrete. Additionally, these materials are used as additives (0.5–2.0%) for production of bricks and ceramics, as components of plasterboard (0.1–0.3%), or for reducing the dust content in road construction [ 12 ].

2016.11.10 1 Introduction Lignin is the second most abundant polymer on Earth and mainly found in hard and softwood trees which contain 20–30 % lignin. From the total pulp production, approximately 70 million tonnes of lignin are available per year.

Lignosulfonate can also be used as concrete admixtures, feed binders, soil stabilizers, dispersants, dye modifiers, air absorbents in mortar, expanders, and asphalt emulsifiers. There are structures such as hydroxyl groups and aromatic groups in lignin, which can react chemically with other polymers, leading to depolymerization products of ...
