Investigation of the microporosity of high performance concrete by proton nuclear relaxation.
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.
