Set Retarders - an overview ScienceDirect Topics

One of the first set retarders that has been used in the manufacture of commercial retarded cement was a blend of borax, boric acid, gelatin, casein, and gum arabic (1973, JPS4860123 A, SAN ES SEKKO GYPSUM). Due to blending problems, this set retarder was exceedingly difficult to handle at bulk cement plants.
