ADMIXTURE FOR MORTAR, MORTAR COMPOSITION, AND MORTAR
To provide an admixture for mortar which, by adding a certain amount of admixture during the manufacture of mortar, has a low impact on properties of the mortar regardless of the construction temperature, has a flowability suitable for construction, and does not cause bleeding, and to provide a mortar composition, and the mortar.SOLUTION: An admixture for mortar comprises an expansive agent, a water-reducing agent, a thickening agent, and an alkali metal sulfate. The viscosity (2 mass% aqueous solution at 20°C) of the thickening agent is 10000 to 100000 mPa s and the thickening agent accounts for 1 to 8 pts.mass of 100 pts.mass of the admixture for mortar.SELECTED DRAWING: None
【課題】モルタルの製造時に混和材を一定量混和することで、施工温度によらずモルタルの性状に影響を及ぼし難く、施工に適した流動性を有し、ブリーディングも生じないモルタル用混和材、モルタル組成物及びモルタルを提供すること。【解決手段】膨張材、減水剤、増粘剤、及びアルカリ金属硫酸塩を含むモルタル用混和材であって、前記増粘剤の粘度（２０℃における２質量％水溶液）が１００００～１０００００ｍＰａ・ｓであり、前記増粘剤の含有量が、前記モルタル用混和材１００質量部に対し、１～８質量部である、モルタル用混和材。【選択図】なし
