Application of Capillary Absorption on Characterization of Structure of Cement Compacts Containing Micro Silica Fume

Abstract:

Effect of packed structure on behavior of capillary absorption was briefly reviewed. Silica fume blended cement was pressed at pressure of 18MPa in a special mould to prepare packed structure. Structure of blended cement compacts was characterized by method of capillary ethanol absorption. Results show that linear correlation coefficient between absorption weight and square root of absorption time for each compact is more than 0.999. Micro silica fume is randomly filled into the skeleton of the compact. With increase of silica fume addition, porosity of the compacts and total length of average capillary pore in the compacts increase, whereas diameter of average capillary pore decreases. Quantified characterization of structure of the blended cement compacts will benefit to research of design and control of cement materials.
