Abstract (en)
[origin: EP0864692A1] Shuttering with filter liner (5) has a hollow chamber (4) corresponding to the support, and concrete is poured-in via a socket (9). The concrete has a water/cement ratio of between 0.4 and 0.6, and immediately after pouring is subjected to excess pressure in the area of the socket, and in the area of the filter liner, to underpressure, until green bond has been achieved and the shuttering can be removed. The concrete contains steel and/or plastic fibres. The excess pressure is at 1-8 kPa, and the underpressure is at 0.3-0.9 kPa. Pressure is applied over a period of 1 - 8 minutes. The shuttering is removed when the water/cement ratio is 0.30 - 0.35.
