Quantities of Materials Per Cubic Meter of Concrete and Mortar Mix Proportions Quantity of materials such as cement, sand, coarse aggregates and water required per cubic meter of concrete and mortar for different mix proportions varies with the mix design of the concrete and mortar respectively.
I was considering mixing my own concrete on a future project. Some questions: 1. What's the correct mix ratio for "C20" concrete? (using ballast) Depending where I look this varies from 5:1 up to 6:1. Any ideas? 2. On my paricular job it will be much more practical to buy 25kg bags of ballast than a big giant bag.
Our concrete calculator allows you to accurately work out the amount of concrete you'll need for your project. Simply add the measurements for your concrete order to the relevant shapes above (you only have to fill in the shape/s you want to use) You can build up a concrete calculation for complicated areas by adding additional shapes of each type.

Jun 01, 2009 · C20 is a general purpose concrete grade of 20 N/mm^2 or 20 MPa. strength. To make it you mix by volume 1 part cement, 2 parts sharp sand to 4 parts of aggregate, say 20 mm gravel for coarse concrete, or 10mm gravel for fine concrete. First confusion comes when all-in ballast is substituted for the separate sand/aggregate ingredients.
I think C25 would gaurantee concrete itself not failing insection. More likely than C15 or C20. My, somewhat uneducated answer then, is that C25 mix is the most likely to pass inspection considering grades C15, C20 and C25. You do not need to consider above C25.
There are different concrete grades for example C15, C20, C25, C30. The grade of the concrete means the concrete compression resistance after 28 days. It is done in Newtons per square millimetre. A concrete of Grade C30 means that the concrete will have a compresion resistance (withstanding a compression) of 30 N/mm2 per square millimetre in 28 days.
