Abstract
A method of forming a lightweight concrete comprising lightweight aggregates (LWA) made from recycled materials and the resulting composition. The lightweight concrete may be formed by adding calcium sulfoaluminate (CSA) cement and a specialized grout to an amount of water in a mixer, wherein a ratio of the water to the CSA cement is 1 quart to every 10 lbs of CSA cement. The CSA cement, specialized grout, and water may be blended to a smooth consistency. LWA may be added to the blended CSA cement, specialized grout, and water, wherein a ratio of the CSA cement to LWA is 60/40 by weight. The mixture of LWA, CSA cement, specialized grout, and water may be poured over a fiberglass rebar. The mixture may be allowed to cure and before being densified with a lithium densifier.

A method of forming a lightweight concrete comprising:
- adding calcium sulfoaluminate (CSA) cement to an amount of water in a mixer, wherein a ratio of the water to the CSA cement is 1 quart to every 10 lbs of CSA cement;
- adding a grout comprising one or more types of Portland cement to the mixer;
- blending the CSA cement, the grout, and the water to a smooth consistency in the mixer for a first period of time;
- adding lightweight aggregates (LWA) to the mixer after a second period of time to form a mixture, wherein a ratio of the CSA cement to LWA is 60/40 by weight;
- pouring the mixture over a fiberglass rebar;
- allowing the mixture to cure;
- and
- densifying the cured mixture with a lithium densifier.
