The spherical shaped particles of fly ash act as miniature ball bearings within the concrete mix, thus providing a lubricant effect. This same effect also improves concrete pumpability by reducing frictional losses during the pumping process and flat work finishability. Figure 3-1: Fly ash improves workability for pavement concrete.

REACTIONS It is usually necessary to idealize the behaviour of a support in order to facilitate an analysis. An approach is taken that is similar to the massless, frictionless pulley in a physics homework problem. Even though these pulleys do not exist, they are useful to enable learning about certain issues.
