The Grading of Fine Aggregate Affecting on Compressive Strength of Concrete - Based Product Having Low W/C

낮은 물시멘트비를 갖는 콘크리트 제품의 압축강도에 미치는 잔골재의 입도분포

Because the grading of aggregate is major factor affecting on compressive strength and durability of concrete, the standard specification of concrete has proposed that the standard grading should be used to make ordinary concrete having good quality. But, it is not suitable for making product having low W/C because of difference between them in manufacturing processes and demanded efficiencies. This study investigated if the grading of the fine aggregate affects on tamping efficiency and compressive strength of concrete-based product. The results of this study showed that the suitable grading for making concrete-based product ranged from C type(FM:2.77) to D type(FM:3.38).
