Amorphous calcium aluminate, as a new type of concrete accelerating agent, has been widely used in a series of concrete rapid setting projects such as concrete tunnel engineering, rapid road repair, rapid demoulding of concrete components, and concrete prefabricated parts.

As a new type of accelerating agent, the main characteristics of amorphous calcium aluminate are super fast setting, small strength loss of concrete in the later stage, extremely low shrinkage of concrete, good durability, strong adaptability to low temperature environment, wide compatibility with other concrete materials, low dosage, high comprehensive cost performance, effectively improving the efficiency of concrete construction, and reducing the comprehensive cost of concrete engineering.

At present, the effects of amorphous calcium aluminate on rapid setting and accelerating setting in low temperature environment are introduced as follows:
Because the internal particle arrangement of the unique amorphous body of amorphous calcium aluminate is irregular, it has a higher internal energy state, so its activity is particularly excellent.  This unique performance advantage can be fully demonstrated in the application of concrete materials. Therefore, in low temperature or extremely low temperature environments, as long as its unique atoms, atomic groups or molecules can activate it, it will also achieve the excellent performance effect in normal temperature environments.
