Disclosed is a system or method for efficiently manufacturing construction materials using carbon nanomaterials. In one or more embodiments, the method comprises creating a blend of carbon nanomaterials, wherein the blend of the carbon nanomaterials includes at least one of a carbon nanofiber, a carbon nanotube, a graphite nanoparticle and an amorphous carbon. The method also includes dispersing the carbon nanomaterials and adding a plasticizer and a sand to the dispersed mixture within 3 minutes. The method also includes adding at least one of water and a cement binding agent to the dispersed mixture after the plasticizer and the sand have been added.
