To provide a mortar composition that enhances CO2 reduction effects through a reduction in cement content in a premix mortar, resulting in a mixed mortar featuring high fluidity and low heat build-up and exhibiting high strength development.SOLUTION: A mortar composition comprises: a binder composed of cement and two or more pozzolana materials including at least blast furnace slag fine powder; first aggregate with a particle size of 3 mm or less; and second aggregate with a particle size of more than 3 mm to 10 mm or less and a percentage of absolute volume of 50-80%. The mass percentage of the cement is 3-16 mass% relative to the mass of the mortar composition. The total mass percentage of the first aggregate and second aggregate is 60-80 mass% relative to the mass of the mortar composition. The mass percentage of the second aggregate relative to the total mass of the first aggregate and second aggregate is 10-50 mass% as expressed by ({[second aggregate mass]/[(first aggregate mass)+(second aggregate mass)]}×100).SELECTED DRAWING: None
【課題】プレミックスモルタル中のセメント量を少なくしてＣＯ２削減効果を向上させ、混練したモルタルが高流動性且つ低発熱性であり、高い強度発現性を示すモルタル組成物を提供する。【解決手段】セメント及び少なくとも高炉スラグ微粉末を含む２種以上のポゾラン物質からなる結合材と、粒径が３ｍｍ以下である第一の骨材と、粒径が３ｍｍ超１０ｍｍ以下であり且つ実積率が５０～８０％である第二の骨材とを含むモルタル組成物であって、セメントの質量割合が、モルタル組成物の質量に対し、３～１６質量％であり、第一の骨材及び第二の骨材の合計質量割合が、モルタル組成物の質量に対し、６０～８０質量％であり、第一の骨材及び第二の骨材の合計質量に対する第二の骨材の質量割合（｛［第二の骨材の質量］／［（第一の骨材の質量）＋（第二の骨材の質量）］｝×１００）が１０～５０質量％である、モルタル組成物。【選択図】なし
