Abstract
An apparatus and method for producing fluid concrete include a first mixer configured to mix at least water and cement so as to make a low fluidity concrete having consistency class ≤S2, a truck mixer that can be configured to mix the low fluidity concrete with further water so as to make a fluid concrete having consistency class ≥S2, and a water supply and at least a cement supply configured so that the apparatus or method can produce fluid concrete. The apparatus and method include a control and adjustment unit, connected to the water supply and at least to the cement supply, configured to selectively control and adjust the introduction of water and cement into the first mixer and the introduction of further water into the cement mixer.

An apparatus for producing fluid concrete comprising:
- at least a first mixer (100) configured to mix at least cement (C) with at least a first amount of water (A1) sufficient to realize a low fluidity concrete (2) having consistency class ≤S2, said first mixer (100) having an outlet section (105) adapted to expel said low fluidity concrete (2),
- a water supply means configured to supply said first amount of water (A1) to said first mixer (100);
- a cement supply means configured to supply cement (C) to said first mixer (100);
- a control and adjustment unit (4), connected to said water supply means and to said cement supply means, configured to calculate said first amount of water (A1) and to selectively control and adjust an introduction of said first amount of water (A1) and cement (C) into the first mixer (100);
- wherein said water supply means is configured to supply a second amount of water (A2) at or downstream of the outlet section (105) of the first mixer (100);
- said control and adjustment unit (4) being configured to calculate said second amount of water (A2) to make a fluid concrete (3) having consistency class ≥S2, and to control and adjust the supply of said second amount of water (A2) at or downstream of said outlet section (105);
- said control and adjustment unit (4) being configured to pre-calculate said first amount of water (A1) and said second amount of water (A2) according to a type of concrete to be made prior to the introduction of said first amount of water (A1) and cement (C) into the first mixer (100);
- and
- a second mixer (200) having a loading section (201) arranged to receive said low fluidity concrete (2) coming from the first mixer (100), said second mixer (200) being configured to mix the low fluidity concrete (2) with said second amount of water (A2) to make the fluid concrete (3) having consistency class ≥S2.
A method for producing fluid concrete, the method comprising:
- supplying at least a first amount of water (A1) and cement (C) to a first mixer (100),
- mixing at least said first amount of water (A1) and said cement (C) into said first mixer (100) for making a low fluidity concrete (2) having slump class ≤S2,
- ejecting the low fluidity concrete (2) from said first mixer (100) at an outlet section (105),
- mixing said ejected low fluidity concrete (2) with a second amount of water (A2) at or downstream of said outlet section (105) to make a fluid concrete (3) having slump class ≥S2, said second amount of water (A2) being supplied to said outlet section (105);
- selectively controlling and adjusting an introduction of said first amount of water (A1) and cement (C) into the first mixer (100) and supplying said second amount of water (A2);
- said first amount of water (A1) and said second amount of water (A2) being pre-calculated according to a type of concrete to be made prior to mixing said first amount of water (A1) and cement (C) in the first mixer (100);
- and
- mixing the low fluidity concrete (2) with said second amount of water (A2) at a second mixer (200) configured to make a fluid concrete (3) having slump class ≥S2.
