An Experimental Study on the Quality of High Flowing Concrete according to Ignition Loss of Fly-ash

플라이애쉬의 미연탄소 함유량에 따른 고유동콘크리트의 품질에 관한 실험적 연구

It is necessary for manufacturing the high flowing to use the fly-ash as binder of concrete, therefore, Quality of fly-ash is very important to the fluidity of high flowing concrete. In this study, it is comparing and investigating the fludity of high flowing concrete used some fly-ash which it's Ignition loss is 2.44, 4.90, 7.10%. As a result of this experimental study, Ignition loss of fly-ash effects the properties of high flowing concrete, such as air content, flowability, passability etc. but even if valve of ignition loss is upper the specification, properties of high flowing concrete such as setting and hardening time, compressive strength etc.
