NCPTT advances the application of science and technology to historic preservation. Working in the fields of archeology, architecture, landscape architecture and materials conservation, the Center accomplishes its mission through training, education, research, technology transfer and partnerships.]]> http://ncptt.nps.gov/2010-annual-report/feed/ 0 http://ncptt.nps.gov/improved-sol-gel-consolidants-for-stone-2002-24/ http://ncptt.nps.gov/improved-sol-gel-consolidants-for-stone-2002-24/#comments Wed, 29 Jul 2009 20:15:01 +0000 NCPTT http://ncptt.nps.gov/?p=3909
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://ncptt.nps.gov/improved-sol-gel-consolidants-for-stone-2002-24/feed/ 1
