SALT-BLOCKING HYDRAULIC COMPOSITION, MORTAR COMPOSITION AND MORTAR CURED BODY
To provide a salt-blocking hydraulic composition having high salt-blocking property and capable of effectively suppressing deterioration due to salt damage.SOLUTION: A hydraulic composition is provided, which has high salt blocking properties and can more effectively suppress deterioration due to salt damage. When a content of each of three components, that is Portland cement, alumina cement, and gypsum, is represented as mass percentages relative to a total amount of the three components, the content of the Portland cement is more than 0 mass% and less than 90 mass%, the content of the alumina cement is more than 0 mass% and less than 80 mass%, and the content of the gypsum is more than 10 mass% and less than 40 mass%, and CaO/Al2O3 mol ratio of the alumina cement exceeds 0.7.SELECTED DRAWING: None
【課題】遮塩性が高く、塩害による劣化をより有効に抑制できる遮塩性水硬性組成物を提供すること。【解決手段】遮塩性が高く、塩害による劣化をより有効に抑制できる水硬性組成物であって、ポルトランドセメント、アルミナセメント、及び石膏の３成分の含有量を、それぞれ当該３成分の合計量に対する質量百分率として、ポルトランドセメント０質量％を超えて９０質量％未満、アルミナセメント０質量％を超えて８０質量％未満、及び石膏１０質量％を超えて４０質量％未満を含み、前記アルミナセメントのＣａＯ／Ａl２Ｏ３モル比が０．７を超えることを特徴とする遮塩性水硬性組成物。【選択図】なし
