A Study On The Rheological Properties of Cement Paste Using Fly Ash and Slag Powder |
Abstract |
This study is aimed for investigating the rheology property and fluidity of cement paste, by changing the substitutional ratio of an admixture, additive dosage of agent and temperature in WP ratio 25~S5%. From the results, the fluidity and rheology. Of paste were different according sorts of powder and additive dosage of agent. And the rheology value of paste using fly_ash increased more than slag in the same temperature. In the range of satisfacting f1ow 350±10mm, rheology value of cement paste was (in the W/P ratio 25~35%) plastic viscosity 0.5~l.85 Pachkqs, yield value l.5~6.5Pa in case of fy_ash plastic viscosity 0.25- 1.8Pa촵s, yield value 0.5 ~6.5Pa in slag. |
