摘要：

Nanoindentation was employed for the characterization of reaction products, mainly N-A-S-H gel, within alkali-activated fly ash samples. Heat and ambient-cured samples from ground fly ash were indented in a grid of hundreds of indents. The intrinsic Young's modulus of N-A-S-H gel was found around the mean value 17.70 GPa, regardless on the curing procedure. Such finding elucidates intrinsic stiffness of mature N-A-S-H gel with different origin. Partly-activated slag, slag and fly-ash particles were further distinguished by histogram deconvolution.
