Highly efficient lignin-based water-reducing agent with high degree of sulfonation and high molecular weight, and preparation method thereof |
| abstract |
This invention discloses a high-performance lignin-based water reducer with high degree of sulfonation and high molecular weight and its preparation method. This water reducer exhibits an excellent water-reducing performance, its water-reducing rate of this lignin-based water reducer reaches 25% at a dosage of 0.70 wt %, which is higher than that of the naphthalene-based water reducer and the sulfonated lignin water reducer prepared by oxidation and sulfonation of alkali lignin, and 28-days compressive strength ratio of the concrete with this water reducer to the concrete without this water reducer is up to 150:100. Furthermore, the water reducer of present invention will not be crystallized in winter, and the concrete iron won't be corroded. The water reducer of the present invention makes the concretes having a low bleeding rate, excellent properties of workability, anti-freeze and anti-carbonization. |
