NANOTECHNOLOGY IN CIVIL ENGINEERING

Mode of functioning

In combination with cement and nanopolymer, the respective material reacts on site and becomes a very stable, yet elastic layer. The correct mixing ratio as well as professional processing are decisive factors.

Work steps

Approx. 40 – 50 kg of soil samples are taken on site.

The soil samples are analysed in the laboratory and the mixing ratio is determined.

If the differences in level are too great, a previous milling operation is necessary in order to subsequently produce the new subgrade with the grader.

A spreader is used to spread the previously determined amount of cement accurately.

In this milling operation, the milling machine is connected to a tank vehicle. The milling machine with injection device sucks the previously determined quantities of water and nanopolymer out of the pre-stressed tanker and injects them directly into the milling chamber (mix-in-place process).

The fresh mixture is pre-compacted.

The plane is created with the planned inclination
