Out of these materials, sodium, calcium and ammonium ligno sulphates are most popular. The amount of plasticizers used varies from 0.1% to 0.4% by weight of cement. At constant workability, the reduction in mixing water by the use of 0.1 to 0.4% of plasticizer is expected from 5% to 15%, which naturally increases the strength.
