C Problematic Fixing C
    
In certain situations, Chemical Anchor is the only solution for fixing a
load. Problematic applications include wet and underwater fixings where
g g
n corrosion and aggressive environmental effects must be considered. n
ori  Environments containing aggressive chemicals or which are regularly ori
h exposed to salt water are also ideal application areas for Chemical h
cy cy
nr Anchor. It creates a total form closure that protects the anchor rod from nr
Ao Ao
e corrosion. Cracked concrete is another problematic application. CF1000 e
alh alh
cT is an ideal solution for anchor fixings in cracked concrete.* Another cT
mi problematic situation involves fixing a load with close axial or edge mi
e distance. C hemical Anchor will hold heavy loads that must be fixed close e
h h
C  to the edge without creating any internal pressure. For these types of C
applications we recommend CF920 (page 3.7) or CF1000 (page 3.8).

About Building Materials

s s s
n Base Materials n n
o o o
ti ti ti
a There are many kinds of base materials. It is important to know their a a
c c c
pli individual properties in order to determine the permitted load and to pli pli
p select suitable anchors. Only in this way is it possible to ensure that p p
A anchors are safe and of a high quality. Concrete, light building materials A A
and masonry (including full stone and hollow brick) are the most
commonly used building materials.
Concrete
s s s
t t t
n n n
e Concrete consisting of a mixture of cement, aggregates, water and e e
t t t
n possibly other additives, is a synthetic stone. It is produced after the n n
o o o
C cement paste hardens and cures. Although it has a relatively high C C
compressive strength, it has only a low tensile strength. Because of
this, steel reinforcing bars are cast in concrete to take up tensile forces.
This is then referred to as reinforced concrete.

g g g
n n n
ri The following factors decide on the concrete type: ri ri
o o o
h • Dry gross density (light concrete, normal concrete, heavy concrete) h h
cy cy cy
nr • Compressive strength nr nr
Ao Ao Ao
e • Place of production, use or ceramic bond condition e e
alh • Consistency alh alh
cT cT cT
mi • Density of the reinforcing bars mi mi
e e e
h h h
C The composition and the processing of the material determine the C C
concrete’s properties. A crucial attribute for concrete is compressive
w strength. Normal concrete without accelerating additives obtains its full w w
e e e
vi minimum compressive strength after 28 days and is ideal for anchoring. vi vi
r After this time has elapsed, the testing procedure defi ned in EN206-1 is r r
e e e
v performed to determine the strength class of the concrete. This is v v
O O O
generally between C12/12 (B15) and C50/60 (B55). For special

t t t
c purposes, higher quality concrete is available, but C20/25 is the most c c
u u u

exceed the figure regarded as admissible (w  0.3 mm) if the concrete
is under a constant load. If the forces acting on the concrete are mostly
constraining, individual cracks may be wider if no additional reinforcement

h h h
C C Anchors are set in both low-strength and high-strength concrete, with C
the cube compressive strength, f , generally ranging from 25 to

w w 60 N/mm2. When using expansion anchors, it is important to take the w
e e e
vi vi curing of the concrete into account. Expansion anchors should not be vi
r r set in concrete that has not cured for more than seven days. The loading r
e e e
v v capacity of anchors can be assumed to be only the actual strength of the v
O O O
concrete at the time the load is applied. If an anchor is set and the load

t t t

u u u
strength determined at that time.
d d d

anchor holes. This can weaken the structure. If this cannot be avoided,
consult the responsible design engineer first.

p p • Compressive strength p
A A This is defi ned by the pressure class: 2, 4, 6, 8, 12, 20, 28, 36, 48 and A
60 N/mm2. The alternative to the pressure class based on the allowable
variation of the compression stress (of the statistic calculation) is not
offered for all brick types in all compressive strengths.
• Bulk density
This is defi ned by the bulk density class: 0,4, 0,5, 0,6, 0,7, 0,8, 0,9, 1,0,
s s s
nt nt 1,2, 1,4, 1,6, 1,8, 2,0, 2,2 and 2,5 kg/dm3. Finer grades exist for certain nt
e e brick types (in multiples of 0,05). While the bulk density designates e
t t t
n n the weight of the brickwork, it can also be used to evaluate heat and n
o o o
C C sound protection. C
The major designation for all bricks is DF. The scale ranges from 2 DF to
25 DF (length x width x height = 61,5 x 30 x 24 cm).

g g g
n n n
Due to the relatively low strength of masonry, the loads taken up locally
ri ri ri
o o cannot be particularly high. Holes drilled for anchors may run into mortar o
h h h
cy cy joints or cavities. Care must be taken to ensure that a layer of insulation cy
Anor Anor or plaster is not used as the base material; the specifi ed anchorage depth Anor
e e (depth of embedment) must be in the actual base material. e
alh alh alh
cT cT cT
mi mi • Before anchoring in masonry, you should obtain accurate information mi
e e regarding which brick (designation, dimensions, allowance, boring, and e
h h h
C C material and compressive strength) and mortar (mortar technology) are C
present.
w w w
• To ensure that anchors in unfamiliar or old masonry are safe, on-site
e e e
vi vi load tests can be performed after consultation with the planner or vi
er er structural engineer. er
v v v

t t edges (e.g. roof truss). Consult the anchor approval specifi cations for t
c c c

brick). There are often large grip holes in the middle of the brick.

s s function. s

t t t
e e e
a load-bearing base material.
