Abstract
The main focus of the current work is to study the effect of phosphorous (PhS) and blast furnace slag (BFS) on the rheological behavior of blended cement. Two blended cement is developed, one with PhS and the other with BFS with 10, 20, and 30% of slags in a laboratory ball with to be well homogenized. The w/c ratio was considered 40%. Portland cement was used as the blank sample. Rheology of the produced blended cement as well as Portland cement was well fitted with the Bingham model. The viscosity of cement shows a constant trend but in the produced blended cement it increased with an increase in the usage amount of slag so that BFS samples show higher viscosity than PhS samples. Results showed that the rheology depends on the type and usage amount of slag. In a constant amount of slag, the BFS samples showed higher amounts in the main rheological parameters compared PhS. The plastic viscosity showed a decrease in the first 5 to 10 min and then an ascending trend was observed due to the progress of hydration in the samples.
