Abstract:
1. A method of forming a cementitious composition, the method comprising the steps of: determining an ash weight of a fly ash sample; selecting a mix strength of greater than or equal to 0.15 and less than or equal to 0.50; calculating an ash rate by subtracting the mix rate from 1.00; calculating a first intermediate factor by dividing the mix rate by the ash rate; calculating an admixture total weight by dividing the ash weight by the ash rate; calculating a mix weight by multiplying the total weight by the mix rate; calculating a rate adjustment factor by dividing a first ash factor less than one by the sum of one plus the intermediate factor; calculating a mix factor by subtracting the rate adjustment factor from the mix rate; and based on the mix factor, selecting a first weight of gypsum, a second weight of a first alkaline component and a third weight of glass, wherein the sum of the first weight, the second weight, and the third weight equals the mix weight.
