| 요약1 |
본 연구는 수도권에서 생산공급되고 있는 콘크리트용 부순모래의 각종 품질현황을 검토하고, 부순모래 대체율에 따른 콘크리트의 특성을 비교분석함으로서 부순모래를 사용한 콘크리트의 배합설계 및 품질향상을 위한 참고자료를 제시하고자 한다. |
| 요약2 |
Generally, aggregate may limit the workability, strength and durability of concrete, and good concrete cannot be made with aggregate of bad property including low strength, bad shape and grading. But recently, it has been insufficient in quantity to collect good natural aggregate because of exhaustion of aggregate resources.
In case of Korea, the using ratio of crushed stone occupies about 97 percent of total coarse aggregate, and ratio of crushed sand occupies about 18.3 percent of total fine aggregate.
This is an experimental study to compare and analyze the properties of crushed sand for concrete in capital region and concrete according to the replacement ratio of crushed sand to improve quality and mix design of concrete using crushed sand.
According to test results, it was found that nearly all the properties of crushed sand satisfied with the value recommended by KS. And it is recommended that FM of crushed sand should be lowered by improvement of manufacture system or grading adjustment should be used because FM of crushed sand was a bit higher. |
