  • Patent number: 10322971
    Abstract: Fast-setting flowable fill compositions for filling ground trenches are described. The compositions set quickly but retain a low strength psi at 28 days. The compositions also reduce bleed water on the surface of the fast-setting flowable fill and therefor enable quicker application of surface repair material, e.g., pavement patches, to the trench. The compositions consist of aggregate, Portland cement, accelerant, water and sometimes air. The compositions may have a compressive strength of between 5 psi and 60 psi after 2 hours, a compressive strength of between 10 psi and 100 psi after 4 hours, a compressive strength of between 75 psi and 500 psi after 28 days, a penetration resistance of between 1.5 tsf and 75 tsf after 2 hours, a penetration resistance of between 4.5 tsf and 200 tsf after 4 hours, and a shrinkage of less than 2% as measured by ASTM C490. Also disclosed are methods of filling a trench with fast-setting flowable fill.

  • Patent number: 9611174
    Abstract: It has been unexpectedly discovered that the addition of a natural or other pozzolan to non-spec fly ash significantly improves the properties of the non-spec fly ash to the extent it can be certified under ASTM C618 and AASHTO 295, as either a Class F or Class C fly ash. The natural pozzolan may be a volcanic ejecta, such as pumice or perlite. Other pozzolans may also be used for this beneficiation process. Many pozzolans are experimentally tested and may be used to beneficiate non-spec fly ash into certifiable Class F fly ash. Additionally, this disclosure provides a method of converting a Class C fly ash to a more valuable Class F fly ash. This discovery will extend diminishing Class F fly ash supplies and turn non-spec fly ash waste streams into valuable, certified fly ash pozzolan which will protect and enhance concrete, mortars and grouts.

  • Patent number: 8338506
    Abstract: Partial oxidation of crumb rubber derived from environmental hazardous waste tires yields surface treated crumb rubber and a gas condensate which are used as blending stocks for making rubberized concrete with substantially improved mechanical strength as compared to the conventional rubberized concrete. The chemically more active rubber surface becomes hydrophilic, so it interacts with the hydrophilic surface of surrounding cement matrix much stronger. The gas condensate co-produced in the partial oxidation reactor consists of mainly active sulfur oxides (R—SOx—R) and serves as an excellent bonding agent to further enhance the bonding strength between the partially oxidized rubber particles and the cement mixes. The mechanically improved rubberized concrete is more versatile than conventional rubberized concrete.

  • Patent number: 8337612
    Abstract: Disclosed are a system, a method and/or composition of environment friendly composite construction material. In one aspect, a method includes providing a mixture of a pozzolanic material and/or a kaolin clay with an activator solution to form an alumino-silicate cementitious material through a resulting geo-polymerization process. The alumino-silicate cementitious material is in the form of a paste. The method also includes processing the alumino-silicate cementitious material to transform the alumino-silicate cementitious material that is in the form of the paste to a form of a powder of the alumino-silicate cementitious material. The method further includes mixing the alumino-silicate cementitious material which is in the form of the powder with water to control a workability of the alumino-silicate cementitious material.

  • Publication number: 20120318173
    Abstract: The present invention provides a composition and a process for the preparation of chemical activated cold setting fly ash building construction materials. The chemical activator is an alkaline aqueous solution of 11.2 to 13.6 in pH and 1.25 to 1.40 gm/cc in density which contains admixtures of different concentrations of hydroxyl, sulfate, acetate and chloride bearing chemical salts of calcium, magnesium, sodium, potassium and aluminum in water medium. The reaction of chemical activator solution and the mineral constituents of fly ash mix develop binding property. The binding matrix of chemical activated fly ash mix is mostly hydrous silica and silicate group of phases which on setting under atmospheric condition attains strength suitable for building construction application. Utilization of fly ash of any source by weight ranges from 80 to 99% in manufacture of building materials including heat and acid resistance and toxic waste disposal products.
