Bauer Concrete Filter Press Testing Bleeding On Concrete

This video is the process testing of bleeding on concrete by pressure Bauer Concrete Filter Press. Below is the description of this equipment.

Concrete filter press consisting of:

Test sieve
50ml Plastic measuring cylinder
250ml Plastic measuring cup
250 mm Aluminum laboratory shovel
Digital stopwatch
Filter paper (100 pieces per pack)
Measuring principle
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.

Measured data
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:

Filtration water

High requirements ≤ 22 ml
Medium requirements ≤ 40 ml
Low requirements ≤ 60 ml
Filter cake

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 are advantageous.
