Review and Download Concrete – Cement:Sand:Gravel App for FREE


The application (available in english and russian) calculates the exact proportions, volume and weight of cement, water, sand and gravel for making concrete with desired characteristics *:

– compressive firmness – classes B7,5..B30 or mark M100..M400
– Mobility (density) of the concrete mix – P1..P5
– Frost-resistance – F50..F1000
– Watertightness – W2..W20

* classes and marks are given in accordance with russian standards

Proportions can be calculated for the concrete on the basis of:

– Gravel and sand
– Only sand
– Ready mix of sand and gravel (S/G mix)

This algorithms are the theoretical basis for the initial selection of the proportions of components only. It is necessary to assess the mobility (thickness) of the concrete mix after making trial mixture. If the mixture has turned too liquid – reduce the amount of cement and water by 5%. If the mixture is too thick – increase cement and water by 5%.
