Æ
Walls up to 4.00 m
Concrete can be poured without
considering the rate of placing.
Æ
Walls higher than 4.00 m
The permissible rate of placing
can be precisely determined
according to DIN 18218:2010-01
using MEVA’s online calcula-
tion programme available on
the MEVA website. Go to www.
meva-international.com -->
Download --> Working Tools -->
Concrete Pressure Calculator.
The concrete pressure calculator
is also available as a mobile app
for use on the construction site.
Or refer to the rates of placing
shown in Tables 10.1 and 10.2.
Note that you cannot use the
tables unless you know the end
of setting of the concrete, t
E
. This
value can be determined on-site
using MEVA’s ultrasonic Solid-
Check measuring device or using
the knead-bag test as described
in DIN 18218:2010-01. Or simply
ask the concrete supplier for the
concrete’s end of setting.
Tables 10.1 and 10.2 show the
recommended rates of placing
according to DIN 18218:2010-
01 that are compatible with
the fresh-concrete pressure and
applicable when using DW 15
tie rods and articulated flange
nuts 15/120 (Table 10.1) or
when using DW 20 tie rods with
articulated flange nuts 20/140
(Table 10.2).
