Methods for producing a blended pozzolan having one or more characteristics, such as one or more chemical and/or physical characteristic, in an established amount or range from two or more different pozzolans. Two or more pozzolans having different chemical and/or physical characteristics can be blended together and a chemical analyzer used to determine a chemical and/or physical characteristic of the blended pozzolan. Upon determining that the chemical and/or physical characteristic of the blended pozzolan is outside the established amount or range, modifying a blending ratio of the two or more pozzolans to restore the chemical and/or physical characteristic to the established amount or range.

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.

Methods of wellbore cementing are provided. A method of designing a cement composition may include: selecting a target heat of hydration for a target time and temperature; selecting one or more cementitious components and a weight percent for each of the one or more cementitious components such that a sum of a heat of hydration of the one or more cementitious components is less than or equal to the target heat of hydration; preparing the cement composition; and allowing the cement composition to set.

A hybrid additive for use in construction materials such as asphalt and concrete is disclosed. The additive includes pellets formed of a plastic or polymer material, and one or more of fibers, pozzolans, nano-carbon tubes, glass, recycled asphalt shingles (RAS), liquid anti-strip, hydrated lime, rejuvenators, cementitious material, and ground tire rubber. Also disclosed are hybrid composite materials useful as paving and building materials, and methods of making the same. The hybrid additives were found to maintain the positive performance aspects of typical asphalt and concrete mixtures, while improving the performance of the mixtures by increasing bonding and strength within the mixture—and therefore increasing useable life and lowering costs.
