  • Low-lead leaching foamed concrete bullet barrier
    Patent number: 6264735
    Abstract: A method of forming low lead leaching foamed concrete is provided. The method includes the step of dry mixing cement with a suspending agent to form a dry mixture. Water is mixed with a fine aggregate to form an aqueous mixture. The dry mixture is mixed into the aqueous mixture to form a slurry. Calcium phosphate is mixed into the slurry until all constituents are throughly distributed throughout the resulting mixture. The density of the resulting mixture is determined and an aqueous foam is added to the resulting mixture until the density of the resulting mixture is reduced to a desired level. Fibers are mixed into the resulting mixture until the fiber is distributed throughout the final mixture. The final mixture is placed into a mold. The mixture is allowed to harden and cure.
