Uses Blocks of Ice in Making Hollow Concrete

According to the Bruckenbau, the productipn’ of hollow concrete bodies completely inclosed, which has hitherto only been possible xftthin certaft limits, is made easier by the new patent system of Stefan Rohm of Munich, who proposes to inclose a block of ice of the required shape in concrete. Of course, small i openings or channels would be left, by means of which the thaw water could escape. In this way It is possible to produce not only small concrete bodies with hollow center but large ones as well. The process can be applied to artificial stone.
