Rapid Set is a fast-setting belitic calcium sulfoaluminate (BCSA) cement. Upon mixing with water, the calcium sulfoaluminate in Rapid Set reacts to create interlocking crystals of ettringite, which cause rapid strength development. This allows the concrete or mortar to be in service quickly, minimizing downtime and allowing a job to be finished ...
