Later improvement of the suspension procedure resulted in consolidants that are much more stable and fluid. Stone treated with the particle-modified consolidant (PMC) increases dramatically in stiffness and strength. Most impressively in a sodium sulfate test, the PMC provided better protection than a commercial silicate consolidant.]]> http://www.ncptt.nps.gov/improved-sol-gel-consolidants-for-stone-2002-24/feed/
