Abstract
The proton spin-lattice relaxation leads to a resolved distribution of four T-1,T-i for the reactive powder concrete. The T-1,T-i frequency dependences are interpreted by a biphasic fast exchange model of proto n and paramagnetic hydrated ions at the surface of the pores. This lea ds to an estimation of the pore sizes.
