Gypsum Content - an overview ScienceDirect Topics

Lerch showed that the optimum gypsum requirement for a properly retarded cement increased with an increase in both C 3 A and alkali content. Using Lerch’s data, the following linear regression equations for optimum SO 3 content have been obtained 222 (7.25) Optimum % SO 3 = 1.841 + 0.095 × % C 3 A + 1.6364 × equivalent % Na 2 O. This treatment was extended to include cement
