Forming is founded.

• Textil „formwork”

Structural elements


• Advantages: - less formwork material and

concrete is needed; reduced

transportation cost and

necessary manpower; reduced

selfweight

- due to water permeability of

textile the cocrete strenght is

increased and air bubbles are

reduced on the surface;

durability is increased


• Disadvantages: - unusual forms; design

processe is longer;

- there are no standard design

methods;

- unusual reinforcing methods

will be necessary;

- hard to convince the

contractors.
