A common mix ratio for good concrete is 1-2-4. So what exactly is a 1-2-4 concrete mix? It's quite simple - one part portland cement, two parts sand, and four parts gravel, along with just enough water to make a damp mixture and the minimum amount to reach a good viscosity for placement. If too much water is added to the mix, the finished strength of the concrete will be compromised and weakened.
It does not matter what kind of measuring device you use for each "part" of the mix - whether you use a spoon, shovel, bucket or wheelbarrow - as long as you use the same thing to measure each portion, you will be able to make good concrete for your projects.
