[Measurement Example] Cement Setting Delay Time

We will introduce a case where the setting delay time of cement was predicted using pulse NMR.

We would like to introduce a case study conducted by Majelica Japan Co., Ltd., which experimentally demonstrated the feasibility of easily comparing setting times using pulse NMR. Two types of dispersions were prepared: one with water added to achieve 50wt% cement, and the other with a cement setting retardant added. The viscosity and relaxation time T1 of each were measured at 60°C. The dispersion with the setting retardant showed an initial viscosity in the low shear region that was about ten times greater, while the initial relaxation time was shorter for the dispersion containing only cement and water.
