In assessing the effect of mica reinforcement on cement paste microstructure, modifications to pore-size distribution, porosity, ~on-evaporable water content, and CH particle size distribution were observed for samples hydrated for up to five years. Microstructural changes were dependent on water-ce

Additions of colloidal silicas and silicates were added to portland cement and tricalcium silicate pastes to assess their pozzolanic reactivity. These materials show early reductions of calcium hydroxide consistent with a rapid pozzolanic reaction. High early strengths were generally observed with s
