Concrete works
Creating gradients
The gap must already exist in the formation, as different concrete strengths lead to cracks.
There are 1-sided, 2-sided and 4-sided gap training.
According to DIN is a proper discharge of the water only after a gap of 1.5% guaranteed.
Most soils with slope given a broom stroke.
Automatic smoothing of concrete:
The unit will be petrol-powered rotary Smoothing machine. These are available as
hand-held devices for small areas and as on sit model to drive with 2 or 3
plates smoothness. Principle is always a first surface of the copying machine.
This is achieved with closed plates, making the surface summarized under and
closed.
Larger bumps can not be compensated, but may also rarely arise additional wells.
The surface gets a "sand paper texture, the best for later application of
composite strokes or vibration clinker in the mortar bed. Thereafter, the
surface is smoothed with several transitions. This is done with four metal wings
which are attached to a cross. The angle of the wings-dipper at each transition
is made steeper, so the surface is always smooth.
Thus, similar to the screed of polished surfaces different structures..
Brush stroke to create
Creating a brush stroke to achieve a rough surface grip and requires a lot of
experience. We bring the broom line directly after the first crossing with the
Wing floats to this is a closed, compact surface guaranteed. The slip resistance
is maximum at R11, but is due to the properties of concrete measure actually
higher than for ceramic coverings.
Surface Allowances
For simple applications, the on-sprinkle of hard material - cement mixture on
the compacted, polished floor to concrete saturation enforced. The material is
then further smooth transitions incorporated into the surface. The improvement
achieved through a reduction of w / z value of the concrete, as well as hard
material through the material itself, which at least the requirements of
DIN1100, Group A, which should correspond. The order quantity is of
environmental and climatic conditions. On average, 3-4 kg/m² upset. The method
is used correctly, concrete composition reliably applicable, but does not meet
the requirements of DIN 18 560 Part 7th
Hard substances strokes in accordance with DIN 18 560, there is material in
three different groups: Group A is minerally, group M is metallic, KS group is
made Elektrokorund / silicon carbide. The wear resistance increases accordingly
from 5.0 cm³ / 50cm² about 3.0 cm³ / 50cm² up to 1.5 cm³ / 50 cm² values of the
test according to DIN 52 108.
The thickness of the screed is standardized and is different depending on the
material.
On most common is the method the screed freshly prepared freshly on the
load-bearing winding and smooth.
Impregnations, sealants and coatings are always on the individual vote. Ask us.
