1. A method for making an admixture for concrete comprising:
providing a mix design for the concrete, the mix design including hewing a cementitious material comprising a pozzolanic material;
providing a carbon nanomaterial comprised of carbon nanoparticles having a predetermined percentage range by mass of the admixture;
wetting and dispersing the carbon nanomaterial in a liquid organic solvent/compound mixture comprised of an amine based compound configured to de-agglomerate and uniformly disperse the carbon nanoparticles; and
selecting the organic/solvent compound mixture and the amine based compound to perform the wetting and dispersing step;
the selecting step including:
providing a dosage of the admixture in the mix design to provide a concentration level of the carbon nanomaterial sufficient to enhance mechanical properties of the concrete including compressive, flexural and tensile strength, and
choosing the amine based compound to produce a reaction with the pozzolanic material,
with the carbon nanomaterial and the amine based compound configured to enhance secondary properties of the concrete including abrasion resistance, shrinkage and permeability.
