Novel hydroxyapatite-based consolidant and the acceleration of hydrolysis of silicate-based consolidants

This paper discusses the effectiveness of hydroxyapatite (HAP) as an inorganic consolidant for physically weathered Indiana Limestone, and as a coupling agent between limestone and a silicate consolidant. A double application is investigated, in which samples are coated with HAP followed by a commercially available silicate-based consolidant (Conservare ® OH-100). To artificially weather limestone, a thermal degradation technique was utilized....
