POLYCARBOXYLIC ACID GROUP ADMIXTURE COMPOSITION FOR SHOTCRETE AND SHOTCRETE COMPOSITION USING IT

摘要

The present invention relates to an admixture composition for shotcrete which comprises polycarboxylic acid, amine-based strength enhancing agents, defoamers, and suspension stabilizers, and a shotcrete composition using the same. The polycarboxylic acid group admixture composition for shotcrete, of the present invention, is suitable for shotcrete which requires formability by increasing viscosity while maintaining the fluidity of a conventional polycarboxylic acid-based admixture.
