Test method for alkali content in antifreeze Shouxian antifreeze price Huoqiu early strength antifreeze water reducer Shucheng antifreeze manufacturer Jinzhai concrete antifreeze Which Huoshan antifreeze is good

The alkali content of antifreeze is measured according to the "Test Method for Homogeneity of Concrete Admixtures" (GB8077-2012). The test methods include flame photometry and atomic absorption spectrometry. , among which the atomic absorption spectrometry method can be found in "Chemical Analysis Methods of Cement" (GB/T176-2008). Most ready-mix concrete companies are equipped with flame photometers, and some ready-mix concrete companies are equipped with atomic absorption spectrometers. The "Concrete Quality Control Standard" (GB50164-2011) stipulates that the main control items of cement quality should include setting time, stability, mortar strength, magnesium oxide and chloride ion content. The main control items of cement with alkali content less than 0.6% should also Includes base content. The benchmark method for measuring magnesium oxide is atomic absorption spectrometry, so some local authorities require ready-mix concrete companies to equip atomic absorption spectrometers.
