Calculation method for pre-judging layering risk of concrete admixture

The invention discloses a calculation method for pre-judging a layering risk of a concrete admixture. The calculation method comprises the following steps: pre-making a concrete admixture compoundingscheme; calculating the total solid matter content, the negative ion total contribution, the total salt content and the product of the negative ion total contribution and the total salt content in thecompounding scheme; judging the layering risk of a compounding admixture; and determining a compounding scheme and compounding a concrete admixture. According to the method, a simple and ingenious calculation method is utilized, whether several concrete admixtures are compounded together properly or not can be evaluated before compounding operation, the method can be used for guiding design and adjustment of a compounding scheme in engineering construction, and the compatibility stability of the compounding admixtures is ensured. In this way, admixture waste caused by layering can be greatlyreduced, resources can be s
