Definitions

  • the present invention relates to a concrete manufacturing plant and a method for manufacturing concrete.
  • Polish patent specification 183166 entitled “The concrete mix manufacturing plant” discloses a plant featuring an aggregate tank to which the central part is permanently fixed in a manner constituting a whole with the tank. Also, the concrete manufacturing plant comprises a conveyor which transports aggregate to the aggregate mixing compartment, while the said aggregate mixing compartment contains equipment for mixing with devices designed for dosing and weighing.
  • the concrete mix manufacturing plant features a connecting unit, connected to the connection located at the bottom of the mixing compartment and to the connection located at the front upper side of the said central part.
  • the combined frame is connected to the upper connection located at the top of mixing compartment and to the bottom connection at the top back of the central part, thus ensuring the possibility of lifting the mixing compartment from the transportation position to the mixing position and lowering it to the transportation position, while leaving all cable connections unaffected.
  • Polish patent specification 38365 entitled “A method for manufacturing dry concretes” discloses a method for manufacturing concretes, wherein cement is mixed with aggregate with no addition of water, and water in a suitable quantity each time specified in the recipe is added on the construction site, and wherein concrete of a desired class is packed into bags in a dry state, marking every bag with the designation of concrete class and the recipe for a required quantity of water according to the proper cement-water ratio.
  • Polish patent specification 103005 entitled “A method for manufacturing cementless concrete” discloses a method for manufacturing cementless concrete from aggregate composition, micro-filler, binder in the form of artificial resin and initiators of polymerization, and possibly with addition of polymerization inhibitors and accelerants, by using a concrete mixer employing the forced mixing method, wherein the manufacturing procedure starts from resin being mixed with additives specified in the recipe.
  • the essence of the invention is that the micro-filler in quantity defined by the ratio required by the recipe is added to the resin previously mixed with additives, and mixed until a fully uniform mixture is obtained, next the aggregate composition is added and the resulting mixture is still mixed in the same concrete mixer.
  • Polish patent 149755 entitled “A method for manufacturing bituminous-mineral mixtures of the bitumen concrete type” discloses a method for manufacturing bituminous-mineral mixtures of the bitumen concrete type, wherein a filler in the form of lime dust is added to the heated mineral aggregate containing 24-45 wt % of 6.3/12.8 chippings, 10-30 wt % of 4.0/6.3 chippings, 20-48 wt % of 0/4.0 fine granulated aggregate, and 14-23 wt % of sand, and then the heated paving grade bitumen in the amount of 6.0-8.0 wt % is added to the prepared mineral aggregate.
  • the essence of the invention is that a straight run bitumen or oxidised bitumen with penetration index of 70 - 200 10" mm or petroleum vacuum distillation residue bottoms are used, all previously treated with the modifying agent manufactured from the by-product obtained during the coke-oven or town gas purification using a dry method, or products of purification of such gases using a dry and wet method, i.e. gas pitch and colloidal sulphur, brought to the air-dry state.
  • the gas pitch is crushed to the grain size below 0.3 mm with the fraction of grain size below 0.075 mm amounting to at least 90%.
  • the modification process is run at the temperature of 383-433 K for 1-6 hours, and one mass part of the modifying agent is used for 1 to 5 mass parts of bitumen.
  • Mineral aggregate heated up to the temperature of 433-443 K can preferably be introduced to the process, and modified bitumen heated up to the temperature of 398-433 K can preferably be added to the mineral aggregate.
  • the quantity of lime dust with the mineral substance contained in modified bitumen preferably amounts to 9-15% of mineral aggregate.
  • the concrete manufacturing plant according to the present invention is equipped with devices designed for mixing and with devices designed for dosing and weighing. Moreover, the plant features the following detachable equipment, arranged as a sequence: hoist winch container, silo container, mixer container, and the cement silo located at the side of the plant.
  • the plant is also equipped with the ash silo located at the side of the plant.
  • the cement silo, mixer container, silo container and hoist winch container are all equipped with lifting devices.
  • the plant has a mobile mixer with two feeding chambers.
  • a method for manufacturing concrete according to the present invention consists in the following procedure: the loading tank is filled using the loading machine and aggregate is transported cyclically to each aggregate silo equipped with dosing flaps until the given silo is full. Simultaneously, the cement balance is filled with cement, water balance with water, water tank with water and plasticizer balance with plasticizers. Subsequently, sand is fed, under control of a control system, from the aggregate silos through the dosing flaps onto the weighing conveyor, and, after weighing a suitable required amount of sand, it is transported by the weighing conveyor to one of the buffering chambers previously filled with the weighed amount of cement.
  • aggregates are dosed, under control of a control system and through the dosing flaps of aggregate silos, onto the weighing conveyor, while, after weighing a suitable amount of aggregate, it is transported to the second buffering chamber.
  • the mobile mixer comprising two feeding chambers is driven under the buffering chamber, while in the first feeding chamber, after filling it with mixture of sand and aggregate from one of the buffering chambers, the mixture is mixed for several, preferably from 1 to 15, seconds.
  • plasticizers are added from the plasticizer balance and the content is mixed again for several, preferably from 1 to 15, seconds.
  • water is added from the water balance and the content is mixed once again for several, preferably from 1 to 15, seconds.
  • aggregate is fed to the second chamber of the mobile mixer, which next, while continuously stirring its content, is driven up to the top of the plant, where the stationary mixer is filled with the mixed content of the first chamber, i.e. with the mixture of sand, cement, plasticizers and water, and the content of the second chamber, i.e. aggregate. Finally, all substances are mixed together in the said stationary mixer and the finished product is discharged from the mixer to the concrete delivery truck.
  • the concrete manufacturing plant according to the invention is easy to assemble and disassemble, therefore can be quickly moved to another location. Also, preparation of the site for the plant is not very much work-consuming. These advantageous features of the plant make it particularly useful for manufacturing concrete for the needs of highway engineering, where the construction site moves forward along with the progress of road construction.
