SPHC5:The Fifth American Historic Cements Conference
September 18-19, 2014
San Francisco & Alcatraz
As historic cement buildings and structures continue to age, the unique challenges related to historic cement identification, preservation and sympathetic restoration have often been overlooked. The purpose of this conference is to enlarge our knowledge of the various cements used in the 19th and early 20th Centuries. During this period of time, usage moved from the use of ordinary, non-hydraulic limes to a variety of hydraulic cements through a dynamic period of innovation. There was both experimentation and discussion of cement materials and their uses. The Fifth American Historic Cement Conference will offer a series of presentations, demonstrations and site visits designed to address materials technologies of this transitional period. Presentations will focus on the following key themes:
Between a Rock and a Hard Place:
Authenticity and Concrete Restoration
Mary A. Jablonski, Principal, Jablonski Building Conservation
Cement History: A number of cement materials were developed and used over the course of the nineteenth and early twentieth century. Presentations will provide insights into use of cements during this period.
