Hollow core slabs have minimal deformation even with high slenderness ratios due to the transversal load distribution and even when the elements do not have any concrete topping.
The produced elements have high load resistances thanks to a low water/cement ratio of concrete from 0.32 to 0.38. Higher water/cement ratios cannot be employed for the production of desired cross sections without the use of expensive formworks.
Even though the low water/cement ratio employed makes the concrete hard to work, NORDIMPIANTI’s machines have no difficulty producing particular element shapes with high levels of reliability.
