Abstract

The effect of the composition of the cement paste with respect to the water:cement ratio and mineral pozzolan content on the effective chloride ion diffusivity is investigated. The diffusivity is found to increase as the water:cement ratio increases. The effectiveness of pyrolized sheet moulding compound in preventing the diffusion of chloride ion is discussed. Pyrolized sheet moulding compound is found to be effective in decreasing the chloride ion diffusivity, and that the diffusivity decreased as the PSMC content of the paste is increased. In addition, the effect of experimental parameters such as sample thickness and concentration gradient, and of modifications to the standard diffusion cell are investigated. A change in the chloride ion concentration in cell 1 of the diffusion cell is found to have no significant effect on the measured chloride ion diffusivity. The sample thickness was found to effect the measured chloride ion diffusivity. (Abstract shortened by UMI.)Dept. of Mechanical, Automotive, and Materials Engineering.
