Zusammenfassung:	The present invention relates to a novel cement additive composition for improving the compression strength of mortar or concrete. In particular, the present invention provides a cement additive composition including a compound in chemical formula 1 and a compound in chemical formula 2. In chemical formula 1, R_1, R_2, and R_3 are independently hydrogen or hydroxyl (C_1-C_6) alkyl, but R_1, R_2, and R_3 are not hydrogen at the same time. In chemical formula 2, R_4 and R_5 are independently hydrogen or hydroxyl (C_1-C_6) alkyl, R_6 is hydroxyl (C_1-C_6) alkyl, and Z is (C_1-C_6) alkylene. 본 발명은 모르타르 또는 콘크리트의 압축강도 물성을 향상시키는 신규한 시멘트 첨가제 조성물에 관한 것이다. 구체적으로, 하기 화학식 1의 화합물 및 하기 화학식 2의 화합물을 포함하는 시멘트 첨가제 조성물을 제공한다. 화학식 1상기 화학식 1에서, R, R및 R는 서로 독립적으로 수소 또는 하이드록시(C-C)알킬이고, 단 R, R및 R모두가 수소인 경우는 제외되고, 화학식 2상기 화학식 2에서, R및 R는 서로 독립적으로 수소 또는 하이드록시(C-C)알킬이고, R은 하이드록시(C-C)알킬이고, Z는 (C-C)알킬렌이다.
