본 연구에서는 배합상 단위수량이 굳지않은 콘크리트의 특성 및 내구성에 미치는 영향을 검토하고자, W/C 40～60%의 일반강도 영역에서 폭넓은 단위수량 변화에 따른 굳지않은 콘크리트 및 경화 콘크리트의 각종 특성과 내구성에 대하여 검토하므로써, 단위수량 변화가 콘크리트 품질에 미치는 영향을 명확히 하고자 한다. |
| 요약2 |
As the durability of concrete tend to be regarded as important, the influence of water content on the durability and quality of concrete become a great concern. For that reason, this study is intended to investigate the influence of water content on the durability and the quality of concrete. According to the results, with an increase of water content, fluidity of fresh concrete increases but air content decreases. When water content is above 180kg/m3, bleeding occurs drastically at early age. As the properties of hardened concrete, compressive strength makes no difference with variation of water content. Length change ratio shows an increasing tendency with an increase of water content. As W/C decreases, neutralization of concrete is slackened due to dense organization, and is accelerated in order of upper, side and lower surface. As W/C decreases, it is also influenced much by an increase of water content. Resistance of freezing and thawing is favorable with an decrease of W/C, and is not influenced by water content. |
