Following draft shows the parameters at different mixer volumes with 0.8 cubic meter
and 1.0 cubic meter:
To come to the standard parameter
liter per (one) cubic meter
, the result with liter per 0.8 cubic meter
can be calculated to one cubic meter. I.e. 64 Liter / 0,8 = 80 Liter/m
3
.
If a volume of e.g. 1.5 cubic meter was used, following calculation will result:
120 Liter / 1,5 = 80 Liter/m
3
To come and compare the exact water content values per cubic meter inside the mixture, it is
possible to take a (representative) sample out of the mixer for kiln drying.
weight of water
The moisture is calculated by:
Moisture in % = -------------------------- * 100%
weight complete
Whereby the weight of water results in the difference of the weight complete before and after the kiln
drying.
The exact water content in liter per cubic meter of the mixture can be calculated with the moisture value
and the raw density of the mixture. This results with e.g. 3% moisture and 1700kg/m
3
raw density in:
Water content in liter/m
3
= (moisture in %) * (raw density) / 100
= 3,0 * 1700 / 100 = 51 Liter/m
3
Typical raw densities for sand, gravel and concrete mixtures are:
Pure sand: approx. 1500 kg/m
3
Sand/gravel mixture: approx. 1700 kg/m
3
Sand/gravel/cement mixture: dependent on water content between 2000kg/m
3
und 2400kg/m
3
A precise measurement of the raw density of the sand/gravel mixture can be
done with standard sample cubes.
