WebbThe cohesiveness of concrete in the fresh state, which is crucial for printing, can be improved by using non-structural fibers such as polypropylene or basalt. The use of fiber reinforcement in 3D printing creates a much-needed segway into the fields of ultra-high performance concretes with enhanced strengths and durability , crucial in aesthetic …
