M25 concrete is known for being strong and lasting a long time, which is why it's good for building things. The recipe for M25 concrete is 1:1:2 – that's one part cement, one part sand, and two parts rocks. If you mix it up like that, it'll hold about 3,625 pounds per square inch after about a month. You usually see this type of concrete in skyscrapers, bridges, and roads that take a lot of weight
Getting the mix right is key to having a good construction project. Check out our cement products to find what works for you.
