Description

technical field [0001] The invention relates to an analysis instrument, in particular to a device, system and method for detecting the alkali content of concrete. Background technique [0002] Concrete raw materials contain alkali (potassium, sodium ions). When the concrete is in an environment with sufficient humidity for a period of time, the alkali (potassium, sodium ions) in the concrete will react with the active silicon in the coarse and fine aggregates, that is, alkali bone Feed reaction. According to "Concrete Alkali Content Limit Standard" CECS 53:93, "Concrete Structure Durability Evaluation Standard" CECS 220:2007 and other relevant standards, the concrete alkali content refers to the content of the equivalent sodium oxide in concrete, expressed in kg / m 3 Calculated, the alkali content of concrete raw materials refers to the content of the equivalent sodium oxide of raw materials, in weight percentage (%). Equivalent sodium oxide content refers to the sum of sod...
