Claim 7:
8. A method of using concrete composition in one or more construction activities, the method comprising:
adding the concrete composition to water in a mixer, wherein the concrete composition comprises from 40 to 60 wt. % of calcium sulfate hemihydrate (CSH), from 4 to 5 lbs/yd3 of polypropylene (PP) fiber, from 30 to 50 wt. % of sand, a retarder, and a superplasticizer, wherein the retarder comprises poly condensed amino acid and calcium (Ca) salt and a quantity of the retarder is between 0.001-0.01% of the CSH by weight, and wherein the superplasticizer comprises polycarboxylate powder and a quantity of the superplasticizer is between 0.5-2% of the CSH by weight;
blending the concrete composition with water in the mixer for a first amount of time; and
mixing the concrete composition with water in the mixer for a second amount of time to produce a concrete mix having a workable consistency.
