at pouring the foundation in our time, masters often order the delivery of the finished concrete. But it may be that such a possibility will not be the builder or the shipping cost will be too high. Then no choice, how to prepare a solution on their own. But for the base housing a private house you can not put all the ingredients "by eye", add water and stir. To do this, the exact proportions needed. It is for their calculations, you can use the calculators, presented in our material.

What is required to use the calculator
Actions are quite simple. But it should be understood that for different grades of concrete required and different ratio of gravel, sand, cement and water. Consider two options.

Concrete M200 - the proportions of components
Concrete this brand is quite suitable for pouring the foundation bath or households. the buildings. Many exactly it is used for single-storey houses. To make a calculation, it is only necessary to make a calculator in the first field the right amount of concrete. Wherein the program calculates the necessary amount for the manufacture of M200 as a PC400 cement, sand, gravel and water, so the cement components and PTS500.

M300 and its production
To calculate the amount of material for this concrete must use the second calculator. The algorithm is not different from the previous one.
And yet you want to give a little explanation of the calculations, if required production of other grades of concrete. Much easier if they will be presented in tabular form.
Some explanations on independent estimates
Take the preparation of concrete of various grades of cement PC400 and PTS500, as well as the recommended water-cement ratio for independent production concrete solutions.
The ratio of materials using PC400
| The planned concrete grade | The ratio by weight of ingredients (cement: sand: gravel) | An exemplary ratio of ingredients by volume (cement: sand: gravel) | The volume ratio of ready-mixed concrete cement |
| M100 (B7.5) | 1: 4.6: 7.0 | 10: 41: 61 | 7.8 |
| M150 (B10 ÷ V12,5) | 1: 3.5: 5.7 | 10: 32: 50 | 6.4 |
| M200 (B15) | 1: 2.8: 4.8 | 10: 25: 42 | 5.4 |
| M250 (B20) | 1: 2.1: 3.9 | 10: 19: 34 | 4.3 |
| M300 (V22,5) | 1: 1.9: 3,7 | 10: 17: 32 | 4.1 |
| M400 (B30) | 1: 1.2: 2.7 | 10: 11: 24 | 3.1 |
Proportions for PTS500
| The planned concrete grade | The ratio by weight of ingredients (cement: sand: gravel) | An exemplary ratio of ingredients by volume (cement: sand: gravel) | The volume ratio of ready-mixed concrete cement |
| M100 (B7.5) | 1: 5.8: 8.1 | 10: 53: 71 | 9.0 |
| M150 (B10 ÷ V12,5) | 1: 4.5: 6.6 | 10: 40: 58 | 7.3 |
| M200 (B15) | 1: 23.5: 5.6 | 10: 32: 49 | 6.2 |
| M250 (B20) | 1: 2.6: 4.5 | 10: 24: 39 | 5.0 |
| M300 (V22,5) | 1: 2.4: 4.3 | 10: 22: 37 | 4.7 |
| M400 (B30) | 1: 1.6: 3.2 | 10: 14: 28 | 3.6 |
The ratio of water and cement in the manufacture of a solution of
| The planned concrete grade | Brand of cement used | |
| PC400 | PTS500 | |
| M100 (V7.5) | 1.03 | — |
| M150 (V10-12.5) | 0.85 | — |
| M200 (B15) | 0.69 | 0.79 |
| M250 (B20) | 0.57 | 0.65 |
| M300 (V22.5) | 0.53 | 0.61 |
conclusion
Taking into consideration the information can be understood that to make a solution with the necessary characteristics for the building and quite possibly yourself. The main thing - do not make a mistake in the calculations. And that theme has become clearer, we offer to see a small workshop on the topic:
