SPRAYING MORTAR
To provide a spraying mortar that has excellent pressure-feeding capability without clogging because the materials are sufficiently kneaded, and generates a reduced amount of dust when spraying, while also exhibiting superior strength development.SOLUTION: A spraying mortar contains a mortar composition, a liquid quick setting agent and water, where the mortar composition contains cement, a quick setting auxiliary agent, a thickener and fine aggregate, the content of the thickener is 0.01 to 1 pt.mass relative to 100 pts.mass of cement in terms of solid content, the grain size of the fine aggregate is such that the content ratio of grains of 0.6 mm or more and less than 2 mm to the total amount of the fine aggregate is 80 mass% or more.SELECTED DRAWING: None
【課題】材料が十分に混練されるため詰まることのない良好な圧送性を有し、吹付け時に粉塵の発生が少なく、強度発現性にも優れる吹付モルタルを提供すること。【解決手段】モルタル組成物、液体急結剤及び水を含む吹付モルタルであって、モルタル組成物は、セメント、急結助剤、増粘剤及び細骨材を含み、増粘剤の含有量が、セメント１００質量部に対し、固形分換算で０．０１～１質量部であり、細骨材の粒度は、細骨全量に対し、０．６ｍｍ以上２ｍｍ未満の粒子の含有割合が８０質量％以上である、吹付モルタル。【選択図】なし
