Concrete with a higher water to cement ratio is more permeable to these substances. The durability is adversely affected. The more water used translates to better hydration, up to a point. The more water the more diluted your paste will be, which adversely affects strength and durability.
The consumption of grinding aid when grinding OPC in a vertical roller mill is typically in the range from 100 g to 300 g per ton of cement. With respect to the use of grinding aid for grinding of OPC, the ball mill system thus has an advantage compared to the vertical roller mill.
Airentraining admixtures, which are used to purposely place microscopic air bubbles into the concrete, are discussed more fully in AirEntrained Concrete. Waterreducing admixtures usually reduce the required water content for a concrete mixture by about 5 to 10 percent. Consequently, concrete containing a waterreducing admixture needs less water to reach a required slump than untreated .
