Either method can be used to determine whether additional water needs to be added to concrete to improve its workability. During the first 10 minutes after mixing, the concrete's rheology will be such that it can be molded into any shape you wish. After this initial period, the concrete hardens and becomes more solid-like.

We use a closed-circuit grinding process to obtain a very finely ground cement. A size particle range of 3 to 30 microns (one micron is a thousandth of a millimeter!) results in the most efficient hydration of cement and better strength properties, including more late strength. The Wonder Cement factory process is now complete.
