DETERIORATION REGENERATION CHART OF STABLE SLURRY AND REGENERANT ADDING METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To easily judge a condition as to where the present slurry belongs, which regenerant is to be added to regenerate the slurry, and what is the deterioration factor by numerically indicating possible patterns as the deterioration of the stable slurry used for diaphragm wall construction or cast-in-place concrete pile construction every management standard. ;SOLUTION: This deterioration regeneration chart of stable slurry is formed by arranging a management item display part 10 for displaying possible patterns as deterioration of slurry every management item (a specific gravity range display part 11, a funnel viscosity range display part 12, a filtered water quantity range display part 13, a pH range display part 14), a regenerant addition pattern display part 20 for displaying addition patterns of a regenerant added so that each management item is within a preset reference value (a pure water display part 12 for displaying addition quantity, a bentonite display part 22, a clay display part 23, a CMC display part 24, a dispersant display part 25, a soda ash display part 26, a sodium bicarbonate display part 27) and a main deterioration factor display part 30 for displaying main factors of the deterioration of stable slurry.;COPYRIGHT: (C)1999,JPO
