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

摘要

A liquid quick-setting admixture which comprises element components including a sulfur component, an aluminum component and an alkali metal component, and a complex forming agent; a shotcreting material; and a method for shotcreting using them. The liquid quick-setting admixture preferably contains 100 parts in terms of SO3 of the sulfur element component, 25 to 110 parts in terms of Al2O3 of the aluminum element component, 2.5 to 50 parts in terms of R2O (wherein R represents an alkali metal atom) of the alkali metal element component, and 2.5 to 75 parts of the complex forming agent. The liquid quick-setting admixture allows a shotcreting work being excellent in quick setting characteristics, and is improved in storage stability.
