The ratios of cement to sand to aggregate for the different gradesof concrete are as follows. M10 has a ratio of 1:3:6.
Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete.
In the above example M-25 Design mix is converted to the familiar 1 bag cement : 2 boxes of sand and 4 boxes of aggregate. While making concrete at site the moisture content of site sand and aggregate must be taken into account in the mixing water and bulking of sand. In the field trial mixes are to be carried out to finalized the mix.

In concrete, aggregate is the granular substance that holds the mixture together in its solid form. Aggregates vary in size and shape, and they can be as finely ground as sand or as coarse as gravel. When mixed with water and cement, these compounds form concrete. Aggregates make up between 60-75% of the volume of the final mixed concrete.
