SONO WZ
Translation of the Original Instructions for Use
Fine C
Grading Curve C
The SONO WZ measures
an insufficient amount of
water and, therefore,
needs to correct the
water content slightly
upwards.
Concrete with a high mortar content, i.e. a lot of sand,
especially with high content of fine material, a lot of
cement.
Standard additives,
standard admixtures and PCEs.
Normal B
Grading Curve B
None or only slight
corrections
Continuous and relatively well-distributed grading curves.
Standard additives, standard admixtures and PCEs.
Coarse A
Grading Curve A
The SONO WZ meas-
ures too much water
and, therefore, needs to
correct the water con-
tent slightly downwards.
1. Concrete with higher k-values and low mortar content.
2. Concrete with continuous and relatively well-distributed
B-grading curves with a special feature:
low target water content, which is less than 160 l/m³, as
well as a lot of PCE high-performance superplasticiser,
which ensures general flowability.
Special U
Gap Grading U
The SONO WZ meas-
ures too much and must,
therefore, correct the
water content down-
wards.
Gap Grading U: i.e. very little or no 2/8 or 4/8 gravel.
Standard additives, standard admixtures and PCEs.
