This study is to investigate the properties of the fluidity of the cement paste due to various and premixing silica fumes, and the results are summarized as following. The flow time of the paste using OPC is fastest among the various factors. It is delayed when FA was mixed comparing to BS. For the effect of the silica fume type, it is presented by order of A, B, and C. The flow of the paste is showed as the opposite tendency of the flow time of the paste, and it is displayed by order of B, A, and C. The viscosity of the paste is pwportional to the flow time of the paste. When FA is used, the orders are C, B, and A. For the BS, they are C, A, and B. All tests are showed for the straight tendency with the ring flow. The Correlation coefficients(R) are -0.847, 0.982, 0.981, and -0.882, so it was analyzed that they have close relationship.. |
