In total:

Density sand construction most likely depends on its content in clay compositions and moisture.
Clean sand with a minimum amount of impurities may have a density of 1300 kg./cub.m.
The sand containing a large amount of water and clay - 1800 kg./cub.m.
The bulk density of the cement under various conditions:
Fresh cement - 1100-1200 kg./m3.
Caked cement - 1500-1600 kg./m3.
The density of crushed stone:
Crushed granite- 1470 kg./cub. m.
Crushed sandstone - 1300 kg./cub.m.
Crushed terrikonovy - 1150 kg./cub.m.
Tuff rubble - 800 kg./cub.m.

Strip foundation free online calculator

The required amount of cement for the manufacture of one cubic meter of concrete different in each case.

It depends on the brand of cement, desirable brand received concrete, the size and proportions of the fillers.
Indicated in the bags.

It is not necessary to repeat how important the design of the house to calculate the amount of building materials for the foundation of the house.
Because the cost of a monolithic foundation comes to the third value of the house.

This service will facilitate the planning and calculation of the basement at home. Help calculate the amount of concrete, reinforcement, shuttering boards for the device strip foundation.

What can you learn:

Footprint of the foundation (For example, to determine the amount of waterproofing to cover the finished basement)
Amount of concrete for the foundation and floor slabs or pouring a basement floor (here will be fun, when, due to elementary errors in multiplication is not enough concrete).
Reinforcement – the number of valves, automatic calculation of weight based on its length and diameter.
The area of ​​the formwork and the amount of timber in cubic meters and in pieces.
The area of ​​all surfaces (for the calculation of waterproofing the basement) and lateral surfaces and base.
Added calculation of the cost of building materials of the foundation.

The same program will draw a blueprint of the foundation.

We hope the service will be useful to those who are building the foundation of their hands, and professionals-builders.


If you need to calculate the construction of the basement without internal partitions (walls), then you need to remove all the checkboxes (options 1 to 9; a, b, c) and set to 0 (zero) in dimensions X1, Y1, X2 and Y2.

Proportion and amount of cement, sand and gravel for making concrete are given the default reference, as recommended by manufacturers of cement.
Just as the price of cement, sand, gravel.

However, the ready-mixed concrete is strongly dependent on the size of fractions of rubble or gravel, cement brand, its freshness and storage conditions. It is known that when long storage of cement loses its properties and quality of cement with high humidity deteriorate faster.

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, crushed stone or gravel.

Specific weight of sand depends on its origin. For example, River sand is heavier than a career.
1 cubic meter of sand weighs 1200-1700 kg on average – 1500 kg.

With gravel and rubble difficult. According to various sources, the weight of 1 cubic meter from 1200 to 2500 kg depending on size. Heavier – more than fine.

So count the cost per ton of sand and gravel you may need to refine or vendors.

However, the calculation still helps to know the estimated costs for building materials for filling the basement. Do not forget another wire for knitting fittings, nails or screws for the casing, the delivery of construction materials, the cost of excavation and construction work.
