양생조건에 따른 경화촉진제 성능검토에 관한 연구

This study, as a part of a research to develop quick hardening concrete using hardening accelerator and at the same time, develop the concrete which prevents initial frost at winter times, the intensity difference could be checked depending on the amount of cement and hardening accelerator and curing temperature through the experiment, and additionally, it could be known that approximately 3～14 hours could be reduced by developing 5 MPa which is the target strength depending on the addition rate of the hardening accelerator relative to the plain formulation.
