Method 3: Take a sample of each in a container/cistern (of equal volume) and fill them The CSA ratio of the M25 is 1: 1: 2, while that of the M30 is mix design (but is generally greater than M25). As the weight of the aggregate is dominating the mixture, the weight of the M30 sample will be greater. Thus, we can differentiate between samples.
