Sodium Lignosulfonate for Concrete Additive Dual-Purpose Water Treatment and Petroleum Additives

Lignosulfonates mainly include calcium lignosulfonate, sodium lignosulfonate, and magnesium lignosulfonate. Calcium lignosulfonate is the most widely used among them. This kind of water-reducing agent has rich sources of raw materials, a simple manufacturing process, and a low price. It accounts for about 80% of the total production of water-reducing agents. However, its effect could be better. It has air-entraining and retarding effects. It is an ordinary water-reducing agent and has a better impact when combined with an early-strength agent.
