Hydrated cement compacts were repeatedly prepared via capillary absorption.The chemical shrinkage was measured to characterize the hydration degree of the cement in the compacts.The fractal dimension was detected to distinguish the packing be-havior of the nanoparticles of C-S-H gel by small-angel X-ray scattering(SAXS) technique.The fractal structure of hardened cement compacts cured under different conditions was investigated.The results show that the hydrated compacts cured under the saturated condition ...
1 IntroductionCement and concrete both are the most widely usedman-made materials.However,the microstructure ofcement based materials is more complex than any othersimply component materials.Powers[1]reported the ear-liest research work on the microstruct
