| Abstract: | Slag powder and cement, which are ground to different particle size distributions, are mixed in certain proportion. The rheological properties and water consumption of standard consistence of the slag-cement paste are tested. Origin software was used to make tri-dimension diagram, in which macro properties were enacted as z axes, the difference between D50 of cement and slag powder enacted as x axes, D50 of slag-cement mixing sample enacted as y axes. The optimum proportion of slag powder and cement was given with the consideration of the workability. |
