- Abstract
- 상온양생에서 재령 6∼12시간에 15MPa∼30MPa의 압축강도를 발현하는 콘크리트를 개발하기위하여, 칼슘이온을 포함하는 경화촉진제를 C3S를 대량으로 함유한 조강시멘트에 혼입한 결과 경화촉진제 첨가량이 증가 할 수 록 조기 압축강도는 크게 향상 하였다. 이는 Ca(OH)2의 성분이 조기재령에서 대량생성이 되었기 때문으로 판단된다.
In order to develop concrete generating compressive strength of 15MPa∼30MPa aging for 6∼12 hours in the room temperature curing, Hardening accelerator containing Ca2+ mixed with rapid hardening portland cement containing C3S in quantity. The result was that the more addictive contents of Hardening accelerator is, the more greatly early compressive strength was improved. That’s because the composition of Ca(OH)2 was mass-produced at early-ages.
