SLURRY-SHAPED QUICK SETTING AGENT, METHOD FOR PRODUCING SPRAY CONCRETE USING THE SAME, AND METHOD FOR CONSTRUCTING SPRAY CONCRETE
PROBLEM TO BE SOLVED: To provide a method for producing spray concrete excellent in quick setting properties and also satisfactory in the consistency of base concrete even if a liquid quick setting agent is used.SOLUTION: Provided a slurry-shaped quick setting agent containing the following components: (A) an alkali metal aluminate; (B) a quick lime based clinker composition; and (C) a gypsum and/or an alkali metal carbonate. Also provided is a method for producing spray concrete characterized in that, after the preparation of the base concrete obtained by being added with the slurry-shaped quick setting agent, the base concrete is press-fed, and the liquid quick setting agent is added with the tip of a spray nozzle.SELECTED DRAWING: None
【課題】液体急結剤を用いても、急結性に優れ、かつベースコンクリートのコンシステンシーの良好な吹付けコンクリートの製造方法を提供する。【解決手段】以下の構成成分を含有してなるスラリー状急結助剤。（Ａ）アルカリ金属アルミン酸塩、（Ｂ）生石灰系クリンカ組成物、（Ｃ）石膏及び／又はアルカリ金属炭酸塩。前記スラリー状急結助剤を添加してなるベースコンクリートを調製した後、該ベースコンクリートを圧送し、吹付けノズル先端で液体急結剤を添加することを特徴とする吹付けコンクリートの製造方法。【選択図】なし
