A Study on Improving Fluidity of Cement Paste

시멘트 페이스트의 유동성 개선방안 연구

In order to meet the high performance of the concrete, the viscosity increases with water binder ratio and amount of powder. because of these problems, we use high performance water reducing agent and low viscosity water reducing agent, but side effects may occur when using large amount of water reducing agent. Therefore, in this research, in order to increase the viscosity, I would like to analyze the change in viscosity and flow characteristics of paste by utilizing fly ash and lung limestone which are generally thrown away without using high performance water reducing agent.
