A new concrete structure is discovered

 

According to furniture shop in Phnom Penh construction materials report, the Vienna University of Technology surprises the world by introducing its new discovery of inflatable concrete without using timber support.

It is reported that the process of this new method is that a concrete-made flat slab gets hard on the ground, then using the pneumatic pressure to bend the concrete to create a stabilized shell.

To simplified the method, professor Johann Kollegger compared the method to that of an orange peel as he said: "It is similar to an orange peel, which is regularly cut and then flattened out on the table,". "We do it the other way around, starting with a flat surface and then bending it to a shell."

With the test from the university, the concrete shell reached to 2.9 meters but the professor stated that it can go higher and up to 50 meters.

This method has been patented and adopted by Austrian Federal Railways on its high speed rail tracks in Carinthia.
