STABILIZER FOR MUDDY WATER CONTROL

摘要

PURPOSE:To obtain the subject stabilizer consisting of a phosphonic acid (salt) and carbonic acid alkali salt, useful for a muddy water shield technique, etc., and capable of stably retaining muddy water. CONSTITUTION:The objective stabilizer containing a phosphonic acid (salt) (e.g. methane-1-hydroxy-1,1-diphosphonic acid) and a carbonic acid alkali salt (preferably sodium carbonate) as active ingredients. The phosphonic acid and carbonic acid alkali salt are generally and preferably used at a weight ratio of 1:5 to 5:1. The stabilizing agent is preferably used at a ratio of 3045wt.% based on cement ingredients in muddy water.
