LIQUID QUICK-SETTING ADMIXTURE, SHOTCRETING MATERIAL AND METHOD FOR SHOTCRETING USING THEM

摘要

The effect of such a high -level integrity spray construction becomes possible to improve the shelf life of liquid admixture to provide a liquid quick-setting admixture , using the same spraying material and a spraying method with a . ; sulfur , a liquid accelerator containing aluminum and alkali metal element components and of the complexing agent , the liquid quick-setting admixture is preferably SO ₃ Al relative to 100 parts of the sulfur element component of the translation ₂ O ₃ in terms of the elements of 25-110 parts of aluminum component , R ₂ O (R represents an alkali metal atom ) and from 2.5 to 50 in terms of parts of the element -containing component and from 2.5 to 75 parts of an alkali metal complexing agent .
