To provide a mortar composition that has proper flowability under a low-temperature environment, and expresses excellent strength in a short time.SOLUTION: A mortar composition contains cement, high-tensile fiber, quick-hardening material, retarder, and water-reducing agent. When the unit quantity of the quick-hardening material for 1 m3 of the mortar composition is A[kg/m3], the unit quantity of the retarder is B[kg/m3], and the unit quantity of the water-reducing agent is C[kg/m3], A is 100-180 kg/m3, B is 1-10 kg/m3, C is 5-30 kg/m3, A/B is 22.0-55.0, and C/B is 2.1-5.5.SELECTED DRAWING: None 【課題】低温環境下において適切な流動性を有し、短時間での強度発現性に優れるモルタル組成物を提供すること。【解決手段】セメント、高張力繊維、急硬材、遅延剤、及び減水剤を含み、モルタル組成物１ｍ３当たりの急硬材の単位量をＡ［ｋｇ／ｍ３］、遅延剤の単位量をＢ［ｋｇ／ｍ３］、減水剤の単位量をＣ［ｋｇ／ｍ３］としたとき、Ａは１００～１８０ｋｇ／ｍ３、Ｂは１～１０ｋｇ／ｍ３、Ｃは５～３０ｋｇ／ｍ３であり、Ａ／Ｂは２２．０～５５．０であり、Ｃ／Ｂは２．１～５．５である、モルタル組成物を提供する。【選択図】なし
