Definitions

  • the present patent application refers to a controlled curing process of concrete parts in cells, and to the curing cell used for the process.
  • Curing of concrete parts can be natural, when the process is performed by simply exposing concrete parts in the open air, or forced, when the process is performed artificially.
  • the temperature reached inside the insulated cells cannot be controlled and, especially in case of high external temperature, the reached value is too high.
  • the purpose of the present invention is to devise a curing process, together with relevant curing cell, used for quick curing of concrete parts within the aforementioned temperature-time limit curves in any time of the year, independently from external temperature variations.
  • concrete parts are stored in the cell and heated at the beginning of the operational cycle. Heat is extracted during the development of the setting reaction, while ensuring air moisture close to saturation (being this a necessary condition for correct concrete curing) and uniform conditions anywhere in the cell.
  • the cell used for the curing process of the invention is characterised by a series of fans for introduction-extraction and recirculation of air, and by a series of nozzles used to spray water and steam; it being provided that these devices operate according to predefined modes according to the specific conditions of the accelerated curing process of concrete parts.
  • the reduction of the air temperature during the concrete setting reaction is obtained by means of the cooling action of a heat exchanger associated with the curing cell, thus eliminating the cyclic change of air (internal-external) in the cell.
  • the cell (1) used for the process of the invention is provided with insulated walls.
  • One of the walls can be removed to introduce and extract stacks of formworks (2) where concrete parts are cast.
  • the figures show the presence of a gap (I) between the formworks (2) of each stack to favour air circulation.
  • each of the formworks (2) has four different parallel cavities in order to form railway sleepers (T).
  • the removable wall of the cell (1) coincides with the roof, which basically acts as a lid (3) that can be handled by means of an overhead crane.
  • a gap (I) (of a few centimetres) exists between the internal side of the lid (3) and the formworks (2) in the upper section of the stack, being the same as the gaps (I) between two formworks.
  • An identical gap (I) also exists at the base of the stack of formworks (2); the stacks rest on two parallel guides (G) fixed to the bottom of the cell (1).
  • the internal side of the front wall (1 a) of the cell (1) is provided with a series of axial fans (4) that ensure air circulation and favour the creation of a continuous laminar flow through the gaps (I) between the formworks (2), as shown by the arrows (F) in figure 1.
  • the series of circulation fans (4) is situated in a narrow space (V) bordered by the front wall (1 a) and a counter-wall (5) with a series of transversal slots (5a) regularly spaced at the same distance as the gaps (I) and aligned with the gaps (I).
  • the purpose of the slotted wall (5) is to ensure uniform air flows through the gaps (I) of the formworks (2), without having to increase the distance between the series of recirculation fans (5) and the stacks of formworks (2).
  • the back wall (1 b) is provided with one or more fans (6) used to extract air from the cell (1) and one or more fans (7) used to introduce external air.
  • Each of the walls (1a, 1b) is provided with two rows of spraying nozzles (8, 9); the first series is composed of nozzles (8) used to spray steam and the second series is composed of nozzles (9) used for water fogging.
  • the first stage of the process of the invention is performed by suitably adjusting the quantity of steam introduced in the cell (1) in order increase the concrete temperature according to the temperature-time curve established for the specific concrete parts from time to time.
  • the temperature increase of concrete parts can be controlled by interrupting the introduction of steam and by operating the nozzles (8) used for water fogging.
  • water fogging spontaneously absorbs the heat generated during the concrete setting reaction, thus reducing the concrete temperature increase.
  • the introduction of water allows to maintain high levels of relative air moisture in the cell (1).
  • the fans (6, 7) start operating to extract hot air saturated with moisture from the cell (1) and introduce cool dry air from the outside.
  • the fans (6, 7) operate in intermittent mode and, if necessary, perform air change cycles while concrete parts are cured in the cell (1).
  • the fans (6, 7) are preferably connected to pipes ending outside the cell (1) and situated at considerable mutual distance.
  • control unit used to set the most suitable operation of components, according to concrete temperature, air temperature and moisture in the cell, temperature and moisture of the external air introduced in the cell, based on the specific operational modes of the process.
  • figures 4, 5 and 6 refer to an alternative embodiment of the process of the invention, which eliminates the need for cyclic air change inside the curing cell (1) and consequently eliminates the presence of the fans (6, 7) used to extract air saturated with moisture from the cell and introduce cool dry air in the cell, respectively.
  • this embodiment of the cell (1) is provided with a heat exchanger (10) fed with cold water or refrigerating fluid in direct expansion.
  • the exchanger (10) is mounted on the internal side of a wall of the cell (1), and the refrigerating unit (10a) is mounted on the external side of the cell.
  • the exchanger (10) starts operating as soon as an excessive temperature increase of the concrete parts being cured inside the cell (1) is sensed, in order to reduce the temperature of circulating air inside the cell (1).
  • the exchanger (10) operates in intermittent mode, just like the fans (6, 7) used in the preceding embodiment of the cell (1).
