Littleton, Colo.-based EdenCrete Industries enters 2017 ramping up production of a liquid admixture that has demonstrated in field trials and early commercial applications a capacity to strengthen concrete at levels sufficient to reduce rebar and portland cement requirements. Dosed at 0.25 gallon to 4 gallons per cubic yard, which typically equates to approximately 3 ounces to 130 ounces per 100 lbs. of cementitious material, the EdenCrete admixture embodies quintillions (one million trillion) of carbon fiber-like tubes, or nanotubes, per gallon. EdenCrete Industries has developed a method to safely transfer carbon nanotubes in admixture form to concrete customers without any risk of health concerns; the resulting product dictates packaging solely in liquid form.Read More
