Funded in part by a grant from the National Center for Preservation Technology and Training.]]> http://www.ncptt.nps.gov/preservation-of-historic-iron-and-steel-in-bridges-and-other-metal-structures/feed/ 0 http://www.ncptt.nps.gov/improved-sol-gel-consolidants-for-stone-2002-24/ http://www.ncptt.nps.gov/improved-sol-gel-consolidants-for-stone-2002-24/#comments Wed, 29 Jul 2009 20:15:01 +0000 NCPTT http://www.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://www.ncptt.nps.gov/improved-sol-gel-consolidants-for-stone-2002-24/feed/ 0 http://www.ncptt.nps.gov/international-preservation-trades-workshop-2009-iptw/ http://www.ncptt.nps.gov/international-preservation-trades-workshop-2009-iptw/#comments Thu, 25 Jun 2009 20:46:58 +0000 NCPTT http://www.ncptt.nps.gov/?p=3512
