Consumption
How much DYNACEM do you need?
It is best to determine the need for Dynacem powder on the basis of the diameter and length of the holes. Approximate DYNACEM quantity required to fill a hole of 1 m depth as a function of hole diameter:
| diameter [mm] | 20 | 22 | 24 | 26 | 28 | 30 |
| Dynacem [kg] | 0,6 | 0,7 | 0,8 | 1,0 | 1,1 | 1,3 |
| diameter [mm] | 32 | 34 | 36 | 38 | 40 | 42 |
| Dynacem [kg] | 1,4 | 1,6 | 1,8 | 2,0 | 2,2 | 2,5 |
Resulting consumption of the silent cracking agent DYNACEM depends on the desired way of demolition:
Breaking
is achieved by placing holes in a square drill pattern, which results in damage of the entire volume of the element.
DYNACEM consumption is high and is approximately equal to:
- rocks: 5 - 20 kg/m3 (kg of Dynacem powder per m3 of rock/concrete)
- concrete: 5 - 15 kg/m3
- reinforced concrete: 10 - 30 kg/m3

Darker cells indicate the consumption for typical combinations of hole diameter and hole spacing being used for hard and very hard rock.
Dividing
is achieved by linear hole distribution, which results in the element being "cut" into blocks fit for loading and transport.
DYNACEM consumption depends mainly on the desired block size and is approximately equal to:
0,5 - 5 kg/m3
