QUICK-HARDENING CEMENT COMPOSITION WITH FROST DAMAGE RESISTANCE
PROBLEM TO BE SOLVED: To prevent the frost damage to a cement composition comprising calcium aluminate, without causing deterioration of strength, regardless of temperature during production or pouring.SOLUTION: This invention provides a cement composition comprising calcium aluminate, the cement composition comprising, based on 100 pts.mass of kneading water, 1-3 pts.mass of air-entraining agent comprising abietic acid as an active ingredient, and 3-10 pts.mass of air bubbles stabilizer comprising polyacrylic acid or polyacrylic acid salt as an active ingredient.
【課題】 製造時や打設の際の温度にかかわらず、カルシウムアルミネートを含むセメント組成物の凍害を、強度低下を起こさせずに防止する。【解決手段】 カルシウムアルミネートを含有するセメント組成物であって、混練水１００質量部に対し、アビエチン酸類を有効成分とする空気連行剤１〜３質量部及びポリアクリル酸又はポリアクリル酸塩を有効成分とする気泡安定化剤３〜１０質量部を含有するセメント組成物。【選択図】 なし
