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 http://ncptt.nps.gov/call-for-presentations/ http://ncptt.nps.gov/call-for-presentations/#comments Tue, 31 Mar 2009 18:54:31 +0000 Jason Church http://ncptt.nps.gov/?p=2789 http://ncptt.nps.gov/call-for-presentations/feed/ 1 http://ncptt.nps.gov/building-dry-stone-retaining-walls-2002-06/ http://ncptt.nps.gov/building-dry-stone-retaining-walls-2002-06/#comments Mon, 02 Mar 2009 18:45:57 +0000 NCPTT http://ncptt.nps.gov/?p=902 http://ncptt.nps.gov/building-dry-stone-retaining-walls-2002-06/feed/ 1 http://ncptt.nps.gov/mechanical-anchor-strength-in-stone-masonry-2008-05/ http://ncptt.nps.gov/mechanical-anchor-strength-in-stone-masonry-2008-05/#comments Tue, 03 Feb 2009 18:17:56 +0000 NCPTT http://ncptt.nps.gov/?p=1293 http://ncptt.nps.gov/mechanical-anchor-strength-in-stone-masonry-2008-05/feed/ 0 http://ncptt.nps.gov/smithsonian-workshop-to-feature-ncptt-research/ http://ncptt.nps.gov/smithsonian-workshop-to-feature-ncptt-research/#comments Sun, 01 Feb 2009 14:00:25 +0000 NCPTT http://ncptt.nps.gov/?p=612 http://ncptt.nps.gov/smithsonian-workshop-to-feature-ncptt-research/feed/ 0 http://ncptt.nps.gov/deterioration-and-preservation-of-porous-stone-chapel-monterey-california-1996-04/ http://ncptt.nps.gov/deterioration-and-preservation-of-porous-stone-chapel-monterey-california-1996-04/#comments Mon, 22 Sep 2008 22:52:54 +0000 NCPTT http://ncptt.nps.gov/?p=1136 http://ncptt.nps.gov/deterioration-and-preservation-of-porous-stone-chapel-monterey-california-1996-04/feed/ 0 http://ncptt.nps.gov/resetting-a-stone-grave-marker-2007-02/ http://ncptt.nps.gov/resetting-a-stone-grave-marker-2007-02/#comments Mon, 22 Sep 2008 20:23:14 +0000 Jason Church http://ncptt.nps.gov/?p=1085 http://ncptt.nps.gov/resetting-a-stone-grave-marker-2007-02/feed/ 1 http://ncptt.nps.gov/retaining-americas-dry-stone-heritage-2002-05/ http://ncptt.nps.gov/retaining-americas-dry-stone-heritage-2002-05/#comments Mon, 22 Sep 2008 20:06:53 +0000 NCPTT http://ncptt.nps.gov/?p=1076 http://ncptt.nps.gov/retaining-americas-dry-stone-heritage-2002-05/feed/ 0 http://ncptt.nps.gov/review-of-the-literature-on-the-topic-of-acidic-deposition-on-stone-1998-09/ http://ncptt.nps.gov/review-of-the-literature-on-the-topic-of-acidic-deposition-on-stone-1998-09/#comments Mon, 22 Sep 2008 20:02:13 +0000 NCPTT http://ncptt.nps.gov/?p=1073 http://ncptt.nps.gov/review-of-the-literature-on-the-topic-of-acidic-deposition-on-stone-1998-09/feed/ 0 http://ncptt.nps.gov/physical-and-chemical-process-of-soiling-and-washoff-at-the-cathedral-of-learning-1998-11/ http://ncptt.nps.gov/physical-and-chemical-process-of-soiling-and-washoff-at-the-cathedral-of-learning-1998-11/#comments Mon, 22 Sep 2008 19:37:18 +0000 NCPTT http://ncptt.nps.gov/?p=1356 http://ncptt.nps.gov/physical-and-chemical-process-of-soiling-and-washoff-at-the-cathedral-of-learning-1998-11/feed/ 0
