Super retarding concrete admixture (abbreviated as super retarding agent, SR agent) is an admixture that can adjust the setting time of concrete at will for a long time (for example, more than *4 hours, or even within *6 hours). It is a new variety researched and developed abroad in recent years. In the past, commercial retarders traditionally used at home and abroad were mostly organic substances Because it has the property of introducing air, excessive addition will cause the reduction of concrete strength and poor hardening, and generally can not be used in situations where the concrete setting needs to be delayed for a long time But the super retarder is not so good. Because it introduces little air, the setting time of concrete can be controlled at will within *4 hours or even *6 hours according to the dosage. Although the setting time is significantly delayed,
