dc.description.abstract이 연구에서는 석회석 미분말(LP)을 치환한 조강포틀랜드시멘트(ESPC) 모르타르의 휨강도와 압축강도의 관계를 평가하였다. 19개의 모르타르 배합은 LP의 분말도(blaine)에 따라 세 그룹으로 구분하였다. ESPC 모르타르에서 LP의 치환율(R_LP)은 각 그룹에서 5% 단위로 0%부터 30%까지 증가하였다. 실험 결과, ESPC 모르타르의 재령 28일 압축강도와 휨강도는 R_LP가 증가함에 따라 감소하였고, LP의 분말도가 높은 모르타르의 경우 감소 기울기가 높을수록 컸다. 이 감소 기울기에 대한 양생조건의 영향은 미미하였다. ESPC 모르타르의 휨강도는 28일 압축강도의 루트승으로 평가할 수 있다. 결과적으로 LP를 치환한 ESPC 모르타르의 휨강도 식을 실험결과들의 회귀분석으로부터 제안하였다.-
dc.description.abstractThis study examines the relationship between the flexural and compressive strengths of early strength portland cement (ESPC) mortars containing limestone powder (LP). Nineteen different mortar mixtures were classified into three groups based on the blaine of the LP. The addition ratio (RLP) of LP for the partial replacement of ESPC varied from 0% to 30% in 5% increment for each group. Test results revealed that both the 28-day compressive strength and flexural strength of ESPC mortars decreased with an increase in RLP, with steeper decreases for mixtures with higher blaine of LP. This pattern was insignificantly affected by the curing condition. Flexural strength of ESPC mortars could be evaluated as the square root of the 28-day compressive strength. Based on regression analysis of the test data, empirical equations were proposed to assess the flexural strength gain of ESPC mortars containing LP.-
