You can also use pressure to compact concrete. However, it is expected to use for very-low workability concrete.

There are two methods of compaction adopted in the field as given below.

1- Hand compaction: a) RODDING, b) RAMMING c) TAMPING

2- Mechanical Compaction: a) INTERNAL VIBRATION b) EXTERNAL VIBRATION c) TABLE VIBRATION. 

Dear Mr. Safiuddin, dear Mr. Alogla,

thanks for your anwers. I think the mentioned ways of compaction won't work with my filigree geometry. External vibration or table vibration would be possible when producing in a concrete factory. I am looking for a method using semi-finished parts (5cm) with added site-concrete at the construction site, but I am afraid external vibration would destroy the semi-finished parts. Internal vibration won't work because of the filigree geometry. The concrete is an "easy compacting concrete ECC" (slump ~60cm). In my project you will find some pictures explaining the geometry. 

Dear Jurgens

You could try 'self leveling, no compaction concrete'.  There are several products that could do the job, if you scan the internet with the bracketed words you may find a range of products.  You could try to minimize the quantity of the cast in situ component to reduce the cost of the finished product. Hope it may help. Best regards

When working on residential or commercial projects the goal is to create an aesthetical pleasing result which is strong as well. For example driveways in residential areas or floors in high traffic commercial zones need to present a good looking finish while also being strong enough to take the weight of multiple vehicles on a daily basis. The advantage of using self compacting concrete in this case is that is requires no vibration and also dries to a shiny finish which requires little extra water.

Up to now I found no satisfying solution for my geometry.

Perhaps I will test this pre-compactor (TU Innsbruck did some tests)

What do you think?

Test with pre-compactor has been done last friday, I added some photos and two videos inside my project "CC-technology".

Good question… Please check this site below.. same question and have good answer... hope it will be helpful for you…

Thank you Hussam Mamuree, the webside explain the methods well. Concerning to my filigree geometry we tested internal and external vibration. Using only external vibration has not been sufficient to deaerate the concrete completely. Using internal vibrator (30mm) is very time consuming because of my geometry, so it's very expensive. By using the pre-compactor inside the flexible concrete tube and additional the internal vibrator (60mm) only at the surface of the ceiling we reached a very good concrete quality within a short working time.

You can find further informations and photos of the concrete pouring within my project "CC-Technology". (last presentation "Dresden")
