잔골재의 점도분포가 시멘트 몰탈의 특성에 미치는 영향 ( The Effect on Properties of Cement Mortar with the Grading of Fine Aggregate )

The fineness modulus (FM) defined as the sum of the cumulative percentages retained on the sieves of the standard series. But thus the same FM can represent an infinite number of totally different size distributions or grading curves. Therefore, this study was designed for analyzing the properties of cement mortar with the various grading curves (cf.fig.1) of fine aggregate which are same FM and limit grading on KSF2526.
