Tunnel concrete shotcrete machine

 

Brief introduction:

 

 

sprayed concrete has replaced the traditional methods of lining tunnel profiles and has become very important in stabilizing the excavated tunnel section. Modern tunneling without sprayed concrete is inconceivable. Sprayed concrete is a single term that describes various components of a complete technology:

 

shotcrete as material

 

shotcreting as placing process

 

shotcrete as construction method

 

These three components define a complete technology which has a long tradition, huge potential for innovation and a great future. The material sprayed concrete is a concrete mix design that is determined by the requirements of the application and the specified parameters. As a rule, this means a reduction in the maximum particle grading to 8 mm, an increase in the binder content and the use of special sprayed concrete admixtures to control the properties of the material.
