Polished lightweight structural concrete and method of formation

A method of forming a lightweight polished 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 in the mixer for a period of time;
• adding lightweight-foamed glass aggregates (FG-LWA) to the mixer after a period of time to form a mixture, wherein the ratio of the CSA cement to FG-LWA is 60/40 by weight;
• pouring the mixture over a fiberglass rebar;
• vibrating and screeding the poured mixture;
• allowing the vibrated and screeded mixture to set to form a set mixture;
• smoothing a top surface of the set mixture with a first type of blades to form a flattened surface;
• hardening the flattened surface with a second type of blades, such that the flattened surface becomes reflective;
• and
• applying a concrete densifier to the reflective flattened surface.
