    摘要: A method for making an admixture in liquid form for concrete includes the step of providing a nanocarbon mixture containing at least two different types of nanocarbon particles, with each type of nanocarbon particle having a predetermined percentage range by mass of the admixture, crushing or grinding the nanocarbon mixture into a carbon powder, and wetting and mixing the carbon powder in a water/surfactant mixture using high energy mixing apparatus. The method can also include blending the nanocarbon mixture with a nano-silica based compound, either before or after the wetting and mixing step. An admixture for concrete includes at least two different types of nanocarbon particles in a water/surfactant mixture having a predetermined percentage range by mass of the admixture. The admixture also includes surfactant and can include a nano-silica based suspension stabilizer having a predetermined percentage range by mass of the admixture.

    摘要: A method for making concrete and concrete structures includes: providing a liquid admixture with a carbon nanomaterial in a liquid aqueous or organic solvent/compound mixture, mixing the liquid admixture with cement and water in a dosage selected to form a concrete mix having a carbon nanomaterial structure having individual carbon nanomaterial particles with a unit cell overlap, and hardening the concrete mix to form a concrete matrix with the carbon nanomaterial forming a 3-dimensional carbon nanomaterial network incorporated into the concrete matrix. The 3-dimensional carbon nanomaterial network has a shielding effect against high frequency electromagnetic pulses and other radiofrequency signals.

    摘要: A method for making an admixture for concrete includes the steps of providing a carbon nanomaterial comprised of carbon nanoparticles and wetting and dispersing the carbon nanomaterial in a liquid organic solvent/compound mixture comprised of amine based compounds configured to de-agglomerate and uniformly disperse the carbon nanoparticles. The method also includes the step of selecting the organic/solvent compound mixture to perform the wetting and dispersing step and to also perform at least one additional function in a particular type of concrete. An admixture for making concrete comprises a suspension of uniformly dispersed carbon nanoparticles having a predetermined percentage range by mass of the admixture in an organic solvent/compound mixture comprising an amine based compound having a predetermined percentage range by mass of the organic solvent/compound mixture.
