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.
摘要
通过测量高性能混凝土和超高性能混凝土各自的质子自旋-晶格弛豫时间，突出了它们在微孔特征方面的差异。为每种配方赋予了一个表面分形维数，并且该维数与硅酸钙水合物的含量存在相关性。
