Electron paramagnetic resonance measurements made during cement hydration are consistent with the osmotic model of cement solidification. Uncharged water‐soluble spin probes probably reflect the growth and cross‐linking of fibrils, where as the formation of a gel coating in the initial stage can be followed with charged spin probes. Retardation and acceleration efects are explained on the basis of concentration differences across the semipermeable gel surface which separates the water solution and the gel coating of the cement grain .
