A Experimental study on th Rheology Properties of Cement-Paste using Fly-ash

플라이애쉬를 사용한 시멘트페이스트의 레올로지 특성에 관한 실험적 연구

This paper tried to catch the fluidity and rheology nature of paste, using the W/P, flay-ash and additional amount of superplasticizing agent as experimental factor. Form result of experiment, as the amount of superplasticizing agent increased, fluidity increased and the rheology decreased. As the substitutional ratio increased fluidity decreased, the rheology tended to increase, additional amount of agent to gain high flowing range is different according to w/p, but this experiment shows about 0.5~1.0% in fly-ash 10~30% substitutional range, 1.0~1.5% in fly-ash 50%.
