The alkali content of the concrete raw material refers to the equivalent oxidation sodium content in the concrete raw materials, by weight percentage (%). And the oxidation sodium content is equivalent to the sum of the oxidation potassium plus the oxidation sodium times 0.658, namely "the equivalent oxidation sodium content= na2o + 0.658 * k2o". the apparatus adopts ion selective electrode method (ise), and it uses the united states imported composite potassium ion electrode and composite sodium ions electrode to rapidly test the alkali content (%) of the concrete (including fresh concrete, wet concrete, hard concrete powdery sample, etc) and the concrete raw materials (including the cement, chemical additive, admixtures, etc.) at room temperatureexecutive standard1. standard for maximum alkali content in concrete cecs 53: 932. standard for durability assessment of concrete structures cecs 220:2007
