Interaction of alkali and alkali earth metal hydroxides with microsilica
Microsilica is inert to trimethylsilylation unless activated by alkaline conditions. In a sodium hydroxide-microsilica model system that simulates the alkaline conditions present in Portland cement, microsilica can be activated to produce polyorganosiloxanes. A calcium hydroxide-micro-silica model system is shown to possess pozzolanic reactivity, and calcium hydroxide reacts with microsilica to form an intermediate C-S-H gel that also can be trimethylsilylated to produce polyorganosiloxanes.
