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 mixture. 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.The aggregates are sand and gravel or crushed stone; the paste is water and portland cement. Concrete gets stronger as it gets older. Portland cement is not a brand name, but the generic term for the type of cement used in virtually all concrete. Cement comprises 10 to 15% of the concrete mix, by volume.Cement Cement & Concrete SA

The Best Ratio of Cement to Sand (for Concrete Crafts)
The results show that the best ratio to use is 3 parts cement and 1 part sand when making small cement crafts. This will result in a smooth, consistent appearance and give you the ability to easily vibrate any entrapped air. This ratio provides plenty of durability for a craft this size.To lay 1 000 bricks you will need: 200 kg cement + 0,55 cubic metres sand. 5.2 Small batches: Use containers such as buckets, drums or tins.
