The abnormal setting time of concrete generally manifests as three types: excessive slow setting, rapid setting, and false setting.
There are many factors that can affect the occurrence of abnormal setting in cement concrete, including concrete admixtures, cement, admixtures, environmental temperature, and wind speed.
From the current quality status of concrete engineering, improper types and dosages of retarders, unsuitability between additives and cement, and environmental temperature are the main reasons for abnormal setting of cement concrete and even concrete engineering accidents.
