Mix ratio of C40 concrete | DIYnot Forums
03-09-2019· jeds. The reason you can't find a prescribed mix ratio for C40 is it doesn't exist. BS5328 only goes up to 25N and anything above 20N can't be mixed with all in ballast. That's not to say you couldn't end up with a mix higher than 25N - just that it's not predictable based on the mix ratio. The only way to guarantee 40N is readymix.
Understanding Concrete Mix Ratios | All Mixes for All,
We’ll go into the ins and outs of mix ratios in more detail below, but to simplify, a good concrete mix ratio for a concrete floor is: 1: cement 2: sand 4: coarse aggregates (for concrete slabs) When mixing, it’s important that the concrete is placed within half an hour to ensure consistency and easy placement.

The strength of concrete is divided into twelve grades such as C7.5, C10, C15, C20, C25, C30,C35, C40,C45,C50,C55andC60. Concrete mix ratios are expressed in two ways: one is expressed in materials used per cubic meter of concrete (Water: Cement: Sand: Gravel), and the other is expressed as a ratio of various materials. for example, C:S:G = 1:2,

What are the Correct Concrete Mixing Ratios - Ratio Chart
When making your own concrete it's important to use the correct concrete mixing ratios to produce a strong, durable concrete mix. Some basic mixing ratios for concrete are 1:2:3, 1:3:3, 1:2:4. These mixing ratios are based on the proportions of cement : sand : stone in that order. The ratio you use will depend on what psi strength you need.
