title: Investigation of the microporosity of high performance concrete by proton nuclear relaxation.
abstract: The difference in microporosity features between high and ultra high performance concrete was highlighted by measuring their respective proton spin-lattice relaxation times. A surface fractal dimension was attributed to each formulation and exhibits a correlation with the amount of calcium silicate hydrates.
