A Study on the Characteristics of Concrete mixed with the Converter furnace Slag
전로슬래그를 이용한 콘크리트의 강도에 관한 연구
Abstract
To examine the applicabilty of the converter furnace slag from iron-works as concrete aggregate respective concrete furnace slag with contents of 20%. 40%, 60%. 80% were mixed with granulated slag, and the strength and stability tests for these specimens were followed. The slump value of the concrete mixed with converter furnace slag was higher than that of the conventional concrete. Furnace slag and granulated slag was increased as the increase of converter furnace content. The strength of the concrete mixed with converter furnace slag and granulate slag increased as an increase of converter furnace content and age. The expansion rate of the concrete mixed with converter furnace slag and granulated slag increased from 0.007% to 0.19% as the converter furnace content changed from 20% to 80%. From the above results in the strength and expansion rate, the concrete with the converter furnace content of 40% was considered to be recommandable for the stable construction of the concrete. Calculated formulas for tensile strength(
본 연구는 전로슬래그를 콘크리트용 골재로 사용할 수 있는 가를 검토하기 위해서 수쇄슬래그에 전로슬래그를 중량비로 20%, 40%, 60%, 80%씩 혼합한 골재로 공시체를 제작하여 강도특성을 고찰하였다. 전로슬래그로 제작한 콘크리트의 슬럼프 값은 천연골재로 제작된 슬럼프 값보다 더 크게 나타났다. 또 수쇄슬래그에 전로슬래그를 혼입하여 제작된 콘크리트는 전로슬래그의 혼입율이 20%, 40%, 60%, 80%로 높아짐에 따라 팽창율도 0.007%, 0.014%, 0.043%, 0.19%로 각각 증가되었다. 따라서 비교적 안정성을 갖는 콘크리트를 제작하기 위해서는 수쇄슬래그와 전로슬래그의 혼입율을 60:40으로 하는 것이 좋을 것으로 생각된다. 또, 수쇄슬래그에 전로슬래그를 혼입하여 만든 콘크리트의 압축강도 (
