Experimental study on the development of super high early strength concrete using C₃S stimulating hardening accelerator

C₃S 자극 경화촉진제를 사용한 초조강 콘크리트 개발에 관한 실험적 연구

In order to develop concrete generating compressive strength of 10MPa~15MPa aging for 6hours 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.
