METHOD FOR DETERMINING ALKALINITY OF HIGH CALCIUM CONTENT ASH Russian patent published in 2003 - IPC

Abstract RU 2199740 C2

FIELD: civil engineering. SUBSTANCE: method involves using alkalinity coefficient Kalk and quality coefficient Kg. Ashes samples are subjected to chemical analysis. Kalk and Kg, and indirect properties like temperature difference Δt in ashes hardening and total free lime content CaOfrtot

in ashes are determined. Kalk and Kg are determined from relationship depending on two parameters Δt and CaOfrtot
. given as equation. The mentioned equation is expressed as follows: . EFFECT: high accuracy and reliability of the method. 3 cl, 2 tbl
