Abstract

It is disclosed a system for extruding cementitious material comprising:- at least one pump (30, 34) of cementitious material;- at least one pump (31) of additive for cementitious material;- a mixing chamber (10) comprising a cementitious material inlet (11) and an inlet (12) of additive for cementitious material; and being configured to mix the cementitious material with the additive for cementitious material forming a printing composition;- an extruder (20) for extruding at least one layer of the printing composition;- a control unit;wherein the extruder (20) comprises at least one temperature sensor (T1), and the mixing chamber (10) comprises at least one pressure sensor (P1) at the cementitious material inlet (11), each sensor (T1, P1) being operatively connected to the control unit, which is configured to adjust the amount of additive for cementitious material in the printing composition.It is also disclosed a method for extruding cementitious material and a system for additive manufacturing of a cementitious material-based structure.
