help on calculating materials for concrete

Specify the required proportions.

E - The required amount of concrete. Stated in cubic meters.
M - How many bags of cement required for 1 cubic meter of concrete.
K - Weight of one bag of cement. In kilograms.

Enter the cost of the materials in your area.

Do not forget to recalculate the prices of bulk materials at cost by weight, not volume.
Proportions and consumption of cement, sand and gravel for making concrete cube of a default given the resource, as recommended by manufacturers of cement.
Likewise, the price of cement, sand, gravel can vary significantly in different regions.

The composition of the finished concrete mixture depends on the size (fractions) crushed stone or gravel, cement brand, its freshness. It is known that during prolonged storage cement loses its properties, and high humidity quality cement uhudshaetsya faster. Please note that the cement in bags can not weigh 50 kg, as it is written. Trust, but verify. How much cement you poured the better to check.

Please note that the cost of sand and gravel is specified in the program for 1 ton. Vendors also announced a price per cubic meter of sand or gravel or gravel.

Proportion of sand depends on its origin, such as river sand is heavier than a career.
1 cubic meter of sand weighs 1200-1700 kg on average - 1500 kg.

Gravel and crushed stone. According to various sources, the weight of 1 cubic meter ranges from 1200 to 2500 kg depending on the fraction (size). Heavier - more than fine.

So pereschityvat price per ton of sand and gravel you will have your own. Or clarify the sellers.

However, the calculation still helps to know the estimated costs for construction materials for the preparation of desired amount of concrete.
