METHOD FOR DETERMINATION OF DIFFICULTY HYDRATED FREE CAO BEING COVERED BY GLASS PHASE IN BROWN ASH

摘要

FIELD: building materials. SUBSTANCE: portion of ash sample is ground to specific surface 1000-1200 cm²/g. Other portion of said sample is hydrated by water. Sustaining time is 25-30 min. Content of free CaO is determined in ground portion of said sample. Content of free CaO being bound with water is determined in unground portion of the sample. Then differences between these values is calculated to determine content of free CaO in brown ash. EFFECT: improves efficiency of method. 1 tbl
