concrete retarding additive calcium lignosulfonate
Calcium Lignosulfonate is a kind of natural anionic surface active agent processed with sulfurous acid pulping waste through advanced production technology.
It can work well with other chemicals and produce early strength agent, slow setting agent, antifreeze and pumping agent.
Main performance:
1. Can reduce 10% of water consumption at least
2. Can improve mixture of the concrete
3. Compression strength improves by more than 15% equally on 3-28 days
4. Have no function of corroding on the reinforcing bar
