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.
What is the mix ratio for C20 concrete? The mix ratio for C20 concrete is 1:2:4. This means 1 part cement, 2 parts sand, and 4 parts coarse aggregates. The exact ratio might …

Let us consider the following concrete mix design example: A concrete with a specified compressive strength of 3750 PSI is required for a slab on ground. The slump should be between 3 and 4 inches, and the placement method is by pumping. The exposure conditions following the ACI 318-19 are briefly a follows: S1, F1, W0, and C1.

Concrete is a composite material composed of water, cement, fine aggregates, and coarse aggregates. When mixed together, these ingredients form a paste that hardens over time, creating a durable and strong building material. Concrete is classified based on its compressive strength, with each classification referring to t…
