We're pretty new to the entire process, and we're not sure of how we will arrive to our results (if the final results will be declared via machine or derived through a certain formula).

In very high-strength concrete mixtures (greater than 70 MPa) the crushing strength of the aggregate can be a limiting factor to the ultimate compressive strength. In lean concretes (with a high water-cement ratio) the crushing strength of the aggregates is not so significant.
