12. Crushing value of aggregate. Determination of the crushing value of an aggregate is helpful to find the compressive strength of the aggregate, whether it is suitable for the concrete work or not. One of the important properties of aggregates affects the overall strength of the structure. 13. Impact value of aggregate

Compressive strength of concrete is the most important property of concrete. This property depends on various factors (constituting material properties and their proportion, method of preparation, curing, test condition). Aggregate Crushing Value (ACV) is one of the important properties of coarse aggregate.
