Concrete filter press consisting of:
- Test sieve
- 50ml Plastic measuring cylinder
- 250ml Plastic measuring cup
- 250mm Aluminium laboratory shovel
- Digital stopwatch
- Filter paper (100 pieces per pack)
The applied pressure for carrying out the test with the CE562 Concrete Filter Press was set to 5 bar, which is kept constant over a period of 5 minutes. Depending on the requirements and experience, it may be necessary to screen the coarse-grained concrete to be examined to a maximum of 8 mm. According to internal experience, this screening can usually be dispensed with up to a maximum diameter of 20 mm.
Due to the numerous experiences with the CE562 concrete fi lter press and in particular the international application, a matrix has now been created which refl ects the following guide values for the fresh concrete stability of the special deep-casting concrete:
- High requirements ≤ 22 ml
- Medium requirements ≤ 40 ml
- Low requirements ≤ 60 ml
The filter cake produced in the test provides additional information on the suitability of the fresh concrete. A low filter cake height and a soft filter cake is advantageous.
