Definitions

  • Embodiments of the present invention generally relate to systems and methods used in the production of concrete. More particularly, the present disclosure relates to systems and methods for using carbon dioxide during the production of concrete.
  • cement and concrete are well known in the art. Concrete has many uses that are highly beneficial in many industries and can be produced to perform many functions. For example, concrete is widely used in commercial construction and for municipal projects. The concrete used in these projects may be pre-heated, pre-stressed, and reinforced.
  • Embodiments of the present invention contemplate novel processes and apparatus directed to the use of carbon dioxide (CO2) in the production of concrete and/or materials used for producing concrete. Applying CO2 to concrete and/or to concrete materials prior to or during production of the concrete according to the systems and methods of embodiments of the present invention has many benefits compared to prior art methods of producing concrete.
  • CO2 carbon dioxide
  • embodiments of the present invention are a reduction in the amount of cement needed during concrete production and decreased energy consumption for the production of concrete.
  • the addition of CO2 to concrete in accordance with embodiments of the present invention results in a reduction in the cement component weight per unit of concrete, typically measured in pounds cement per cubic yard of concrete or kilograms cement per cubic meter of concrete. By weight and by volume, cement is typically the most expensive part of the large components of the concrete mix. By treating the concrete with CO2, the total cost of a cubic meter or cubic yard of concrete is reduced.
  • the total cost of production of concrete is reduced by adding CO2 to the concrete, allowing a cubic yard of concrete or cubic meter of concrete to be produced at a lower total cost.
  • a further benefit of the addition of CO2 to the concrete mix is an increase in the ratio of water to cement that may be used to produce the concrete.
  • Freshly mixed concrete produced using the methods and systems of the present invention achieves a required slump, a measure of the workability of freshly mixed concrete, although the ratio of water to cement used to produce the concrete is greater than is possible for concrete produced using known methods.
  • the present invention improves the consistency and workability of the freshly mixed concrete.
  • the addition of CO2 to concrete according to embodiments of the present invention measurably improves the break strength of the concrete, a key physical property of concrete, compared to control samples of concrete produced using known methods.
  • Break strength tests of concrete samples produced and treated with CO2 using the methods and apparatus of embodiments of the present invention show that the variability of break strength is reduced between 50% and 80% compared to concrete produced using other known methods. Further, treating concrete with CO2 results in a more consistent concrete mix.
  • the present invention allows concrete producers and users to formulate more precise concrete mix designs for the desired structural properties of the concrete treated with CO2.
  • Another benefit of the present invention is a reduction in the temperature of the fresh mix concrete.
  • liquid carbon dioxide When liquid carbon dioxide is injected from a tank or storage container into a mixer, the liquid carbon dioxide changes phase to both gaseous and solid carbon dioxide at atmospheric pressure. At atmospheric pressure, the solid CO2 must be ⁇ 109° F. ( ⁇ 78.5° C.) or less. Consequently, CO2 applied to mixing concrete according to embodiments of the present invention cools the fresh concrete mix in proportion to the amount of CO2 injected into the concrete mix. Reducing the temperature of fresh mix concrete is known to increase the strength of the cured concrete. Methods and apparatus to reduce the temperature of concrete are generally known in the art as disclosed in U.S. Pat. No. 8,584,864 and U.S. patent application Ser. No. 14/056,139 which are incorporated herein in their entirety by reference. Thus, by cooling the concrete mix, embodiments of the present invention increase the strength of the resulting cured concrete.
  • the systems and methods of embodiments of the present invention also produce concrete with reduced permeability and a reduced degradation rate, thereby increasing the service life of the concrete and structures made with the concrete.
  • Those of skill in the art know that the carbonation level of concrete increases over time, reducing the permeability of the concrete. In other words, the small interstitial spaces within the concrete are filled in by the carbonation products from the carbonation reaction.
  • the present invention speeds up the carbonation process resulting in an initial concrete product with less permeability compared to concrete produced using known methods.
  • a less permeable concrete is less susceptible to environmental degradation which occurs when oxygen, water, and other liquids or contaminates permeate the concrete and cause oxidation (or “rust”) of the steel reinforcing members within the concrete. Normal freeze/thaw cycles can also reduce the strength of the concrete permeated by oxygen, water, and other liquids by creating fissures within the concrete structure.
  • structures made with concrete produced by embodiments of the systems and methods of the present invention have an increased service life.
  • Embodiments of the present invention also help decrease the CO2 footprint of cement and concrete production by trapping and/or sequestering CO2 in the concrete and reacting with CO2 during hydration of the cement during the concrete mixing process.
  • the amount of energy consumed during the production of concrete using methods and systems of the present invention is also reduced because the amount of cement required to produce a given amount of concrete is reduced.
  • the present invention reduces emissions of CO2, a known greenhouse gas believed to contribute to global warming, during the production of concrete.
  • embodiments of the present invention further reduce energy consumption and greenhouse gas emissions of cement manufacturers.
  • this application may take the form of entraining, sequestering or consuming CO2 during the production of concrete or concrete material(s) used in the production of concrete.
  • the system and method may be performed “in-situ” where the materials for producing concrete are stored (such as in large containers or “pigs,” or other storage devices at the production site) or may alternatively be performed through a separate sub-process.
  • Embodiments of the present invention trap and/or sequester CO2 in the concrete resulting in reduced CO2 emissions during the production of concrete and decreasing greenhouse gas pollution.
